referring now more particularly to fig1 of the drawings , there is shown an illustrative body suit 1 in accordance with the invention which in this case particularly adapted for use with infants and small children . the illustrative body suit 1 , which is shown in the unfolded condition looking at the inside , includes a back piece 2 , which extends as a single piece into a right front piece 3 and a left front piece 4 . the two front pieces 3 , 4 , are shown separated from the back piece 2 by imaginary broken lines 5 . in a practical embodiment , the two front pieces , 3 , 4 are tailored with no lateral seam . the terms “ front piece ” and “ back piece ” are used herein the traditional parlance of the garment industry . at the lower end of the back piece 2 , a flap or crotch piece 6 is tailored which passes through the crotch when wearing the garment . at the upper end of the two front pieces 3 , 4 arm cutouts 7 , 8 are formed from which sleeves 9 , 10 emerge , which are sewn about the cutouts 7 , 8 . an upper edge 11 forms a neck cutout when in the wearing condition . the right front piece 3 is bounded at the side by a straight edge 12 , which starts at the upper edge 11 for the neck cutout and extends to the crotch piece 6 at approximately at pant 13 , i . e ., at a height characterizing the transition between the back piece 2 and the crotch piece 6 , with a curved tailored edge 14 . the left front piece 4 passes with a rounded edge 16 into a straight , downward running edge 17 , which in turn passes at the height of the corner 13 in a rounded segment 18 into the curved edge 19 , which at the same time also represents the side boundary of the crotch piece 6 . the transverse dimension of the front piece 4 is larger than that of the front piece 3 so that when worn the front piece 4 can fold across the side of the front piece 3 away from the body . to secure the body suit 1 in the closed condition , snap button top halves 21 are provided along the edges 17 , 18 . the snap button top halves 21 correspond to snap button bottom halves arranged along the tailored edge 12 . the snap button have bottom halves in the form of rivet rings 22 , which are used to secure the snap button halves to the body suit 1 . additional snap button top halves 21 are present on the lower free end of the crotch piece 6 . these correspond to snap button top halves that are sewn onto the outside of the two front pieces 3 , 4 which are not visible in the figure . instead of the snap buttons shown , buttons , hooks or tentacle closures alternatively could be provided to close the textile garment . in carrying out the invention , the body suit 1 serves to support the sensors in a manner for reliably monitoring vital functions of the wearer . the sensors in this case include a temperature sensor 25 , three electrodes , 26 , 27 , 28 for tapping action currents of the heart in two channels , and two strain gage measuring strips 29 , 30 , indicated by broken lines in fig1 , to detect the chest breathing and abdominal breathing . additional sensors in the form of electrodes can be included to measure the skin resistance or the transpiration . the base material for the body suit 1 , including the arms 9 , 10 , consists of a knitted fabric . the knitted fabric can be a tricot , a hosiery knit , or a knit fabric . the advantage of the knitted fabric is that the textile fabric can stretch in both axial directions and has a certain recoil ability . due to this property , a tighter fit is assured without a tendency to form folds during movement . the fit to the body can be further improved by knitting in yet another elastomeric thread , for example spandex , to a slight extent . the method of knitting in spandex threads is known in the art and thus need not be discussed in detail . the elongation measuring strip 29 is located in a belt 31 , which is designed as a knitted tube . the stitch wales lie in the lengthwise direction of the belt 31 . the belt 31 is sewn to the body suit 1 at approximately one site 32 , indicated by a broken line . the belt 31 starts in the vicinity of the edge of cut 12 and reaches , as shown , across the edge of cut 17 . it lies perpendicular to the lengthwise axis of the human body when the body suit 1 is being worn . furthermore , it is dimensioned such that when the body suit is worn it is led out from between the two front pieces 3 , 4 . to fasten the free end of the belt 31 , another snap button 33 is provided , corresponding to snap button sockets located on the outside of the front piece 3 or the back piece 2 which in this instance are concealed in the drawing by the belt 31 . since the belt 31 is designed as a tube , the elongation measuring strip 29 can be located on the inside of the belt , which helps protect the strip 29 from mechanical damage . moreover , skin irritation which might be caused by the elongation measuring strip and its edges is also avoided since there is a layer of fabric between the skin of the wearer and the elongation measuring strip 29 . the material of the fabric can be the same material as used for the main part of the body suit 1 , namely , essentially cotton or any skin - tolerated fabric based on synthetic fiber that ensures good wearing comfort and takes up moisture . in the vicinity of the arm cutout 7 , the electrode 26 is located on the belt 31 , as shown . it is placed such that when the body suit 1 is worn , the electrode lies against the body at the location which can be utilized in electrocardiography . the second electrode 28 is likewise located in a prolongation of the belt 31 at the same body height . another belt 34 runs transversely to the back piece 2 at a height corresponding to just above the belly button of the user in the worn condition . the belt 34 is constructed the same as the belt 31 and it is secured in similar fashion . the tubelike belt 34 is sewn firmly to the right front piece 3 , the back piece 2 and the left front piece 4 up to a point 35 . the adjoining segment forms a free lap piece , containing the elongation measuring strip 30 . the free end of the belt 34 is provided with a snap button 36 for keeping the belt under tension against the body of the wearer . the belt 34 also has an electrode 27 for tapping the action currents of the heart . its position corresponds to the position required for the two - channel tapping of heart currents . extremely fine , insulated wires , as shown by broken lines 37 in fig1 , are used for tapping the electrical signals from the electrodes 26 , 27 , 28 , the thermistor in the form of an ntc resistor 24 ( 25 ? ), and the two elongation measuring strips 29 , 30 . these wires , because of their fineness , are extremely fragile . in order to protect them mechanically , they are part of a fabric strip 38 , which is woven as a strip with closed edges which cannot become frayed . in this strip , the insulated wires 37 form parallel warp threads alongside each other . to the right and left of these centrally located electrical wires there are woven in warp threads 39 consisting of cotton or synthetic fiber which for the most part is not stretchable . weft threads 40 of the strip 38 also consist of unstretchable cotton , synthetic or mixed fibers . the ribbon cable obtained in this way runs next to the edge of cut 12 , being covered by a sewn - on flap 41 . at the height of the belt 34 , a first segment branches off at right angles , runs into the belt 34 , and makes appropriate contact there . another part of the ribbon cable 38 bends over , roughly underneath the electrode 28 , in order to make contact with the sensors contained in the belt 31 , including the electrode 28 . the lower free end of the striplike cable is provided with a plug 42 in order to connect the sensors electrically to an evaluating electronic system . due to the special arrangement of the striplike cable 38 , it runs when worn through the center of the body in the direction of the legs , thereby producing the least possible hindrance , and also minimizing the risk of the cable getting torn by the movements of the wearer , especially an infant . it can be led out in the leg cutout and does not hinder the infant in its natural movement , even if the child is rather big and is turning in bed . there is no risk of strangulation . at the same time , the body suit 1 by completely enveloping the thorax and abdomen ensures that the various sensors remain placed at the proper location on the body . they cannot shift in either the circumferential direction or the longitudinal direction . the pretensioning also ensures the necessary contact pressure so that the electrical connection between the electrodes 26 , 27 , 28 and the skin surface remains in place . the tight fit of the belts 31 , 34 means that the elongation measuring strips 29 , 30 will also transmit the expansion resulting from chest and abdominal breathing . this ensures proper monitoring of the wearer &# 39 ; s breathing . the elongation measuring strip 29 , 30 is shown in detail in fig2 . fig2 reveals the cut - open tubelike belt 31 , with a u - shaped strip 43 being arranged on the side of the flat side of the tube facing the body of the wearer . the strip 43 has a first leg 44 parallel to the lengthwise dimension of the belt 31 . at the end corresponding to the free end of the belt 31 , the first legs 44 connects with a back segment 45 , which connects to a leg 46 that extends parallel to the leg 44 . at the free ends of the two legs , the corresponding electrical lines 37 are hooked up . the construction of the elongation measuring strip 29 , 30 , as shown in the cross section in fig3 , includes an insulating layer 47 arranged on the inside of the belt 31 . the insulating layer 47 follows the course of the strips 44 , 45 , 46 . the insulating layer 47 is insulating in the electrical sense , i . e ., it is extremely high - resistive . in the middle , an electrically conductive layer 48 is arranged on the insulating layer 47 . the electrically conductive layer 48 is narrower than the insulating layer 47 and continues uninterrupted the entire length of the strips 44 , 45 , 46 . the internal construction is shown enlarged at 49 . the electrically conducting layer 48 is covered by another insulating layer 51 , as can be seen from the cross sectional drawing in fig3 . in this way , the electrically conductive layer 48 is enveloped on all sides and makes electrical contact only at the ends of the strips 44 , 46 via the conductors 37 . the material for the layers 47 , 48 , 51 is an elastomer which is skin - tolerable and also preferably nonallergenic . suitable materials are polyurethane , silicone and fluoro - elastomers . moreover , these elastomers have the property of being very stretchable and not hindering the stretching ability of the belt 31 , which serves as a substrate for the elongation measuring strips 29 , 30 . the elastomers used have a greater stretching ability than the textile substrate on which they are fastened , protects the elastic structure against overstrain . the elastomers , for example in the case of silicone , are distinguished by very slight rigidity and a low shore a - hardness of less than 20 . if the layer has a slight thickness of less than 1 mm , the stretching of the textile substrate will be insignificantly hindered by the elastomer . furthermore , the elastomer , depending on the application , should be at least warm water resistant so that the body suit can be washed . in the case of higher requirements for sterility , hot water resistance may also be required in order to disinfect the body suit 1 . if necessary , a sterilization in the autoclave might even be desired , which further increases the demands on the temperature and steam resistance of the elastomers . the same holds , of course , for the insulation of the connection wires 37 . since the above - mentioned elastomers are essentially electrical nonconductors , the conductivity of the central conductive layer can only be maintained by embedding conductive particles , such as carbon particles 52 , in an appropriate amount . the carbon particles are embedded in a proportion such that a specific resistance of around 25 ohm cm is created . preferably , the specific resistance varies in a range between 2 ohm cm and 1 kohm cm . due to the electrically conductive particles embedded in the elastomer , the specific resistance of the electrically conductive resistance layer 48 varies as a function of the stretching . since the elongation measuring strip 29 , 30 has a u - shaped configuration , a higher useful signal will be generated because two strips lying parallel to each other in the lengthwise direction will be stretched at the same time . the resulting signal is larger than if only one strip is used . an even greater sensitivity is achieved by having more than two strips in parallel with each other so long as space conditions permit . the contacting preferably occurs by embedding the ends of the connection wires 37 with the insulation peeled off in the not yet hardened elastomer of the resistance layer 48 . then the insulating elastomer layer 51 is placed on this . in place of carbon particles , appropriate metal particles can also be used . the metal particles should remain electrically conductive inside the elastomer , even at the surface , and not be oxidized into a nonconductive layer at the surface . the electrodes 26 , 27 , 28 are placed on the inner top side of the body suit as a conductive layer and have the shape of a circular disk with a diameter of around 1 . 5 cm . they are constructed in similar manner to the resistance layer 48 , consisting of an elastomer 53 in which once again electrically conductive particles 52 are embedded . the connection wire 37 is embedded at one stripped end 54 in the not yet hardened elastomer mass and is thereby both electrically contacted and mechanically secured , as is also the case with the elongation measuring strips 29 , 30 . the surface can be smooth or structured . in the case of a structuring , the surface consists of an arrangement of tetrahedra or pyramids or an imitation textile surface , which improves the transport of sweat , the wearing comfort , and the draping quality , as well as the contact resistance . the electrode can also be made entirely of textile by working electrically conductive yarn or threads into a textile surface . this surface can either be sewn on in the specified shape and size or be worked in as a tarsia when knitting the belt . since what is important for the electrode is not a change in resistance , but a lowest possible resistance , the proportion of electrically conductive particles 52 may be rather high (& gt ; 50 % by volume ). instead of carbon particles , metal particles again also can be used . in selecting the suitable material , however , the metal particles should not have any electrically insulating oxide layer , even after the hardening of the polymer . otherwise , they would merely serve as a nonconducting filler which would defeat their purpose . in the embodiment of fig1 , the body suit 1 can be produced , for example , by circular knitting , followed by cutting out and hemming of the edges . the connection cables are produced as separate strips and then sewn on . fig6 shows an embodiment produced by the so - called “ fully fashioned ” method . this is a special flatbed knitting technique in which the desired structure ( except for the sleeves 9 , 10 ) is produced in the particular desired form in a single work step . one achieves a different stretching ability in the back region 2 because , as is shown , individual threads 60 lie there as a float in the knitted fabric 23 , i . e ., they are not knitted off . float means in the garment industry that the threads lie in the direction of the stitch row without forming stitches . this reduces the stretching ability on account of the lack of a stitch structure . furthermore , it is possible , as shown at 61 , to knit conductive threads in directly so as to achieve the contacting of the sensor 26 . the knitted - in threads at first run in the direction of the stitch row , i . e ., they form stitch rows , or they are stitched together with the base material as plaiting threads . in the vicinity of the side edge 12 , these conductive threads that form the connection wires are then incorporated in the direction of the stitch wale , and emerge as free ends at a stitched - on bracket 62 so that they can make contact there at a plug , corresponding to the plug 42 . an elongation sensor 30 is connected in a similar manner , in that several wires are knitted in at a distance from each other , and thus are electrically insulated from each other , in order to accomplish the electrical contacting . preferably several conductors are knitted in for each electrical line in order to achieve a certain redundancy so that the electrical contact is not lost if one of the conductors gets broken . in order that body sweat absorbed by the textile base material does not produce any unwanted short circuiting between the conductors , the wires each are insulated from each other and preferably are stitched in . finally , special pattern techniques , as are known from the jacquard process , can be used to knit in structures , as indicated at 62 , in order to achieve , for example , a shiny metal contact surface . the advantage of the technique for making the body suit as shown in fig1 lies in the lesser requirements in the complexity of the knitting and weaving machines used . on the other hand , a number of cutting and sewing steps are necessary . the cutting and sewing work is significantly reduced in making the body suit in fig6 . on the other hand , more complicated textile machines are required . the fundamental principle of the invention has been explained above by means of a body suit . this body suit can be used for infants , small children , or even adults . the essential benefit is that it can be used both for bedridden patients / persons , and it can also be worn during normal activity or sports . another implementation of the invention is depicted in fig7 and 8 , which illustrates the type of garment by means of which the monitoring is carried out is not limited to body suits . instead , fig7 shows pants 63 which are supported by means of suspenders 64 which are joined to each other by belts 65 . the belts 65 carry sensors 30 , shown by broken line , on the side facing the body . the belts , in turn , run in the direction transverse to the lengthwise axis of the body and lie against the body due to their natural elasticity . additional sensors can easily be placed on the side of the suspenders 64 facing the body . due to the pretensioning of the belt 65 running in the chest region , the suspenders are likewise held in close fitting relation against the surface of the body in order to take measurements in a manner similar to that explained in connection with the body suit in fig1 . fig8 shows overalls with a bib 66 on which sensors 30 are placed on a side facing the body . the belts 65 emerge sideways from the bib 66 and surround the body of the wearer . they elastically press the bib 66 with the sensors 30 located on its inner side against the skin surface , similar to that described above . furthermore , suspenders 64 emerge from the top edge of the bib 66 and lead to the waistband of the pants 63 . the natural weight of the lower part of the pants 64 prevents the sensors arranged on the suspenders 64 of the belts 65 from shifting upward in undesirable manner while being worn and leaving their prescribed location on the body . it will be understood that the garments shown in fig7 and 8 are also especially suitable for monitoring the bodily functions of people carrying out their normal activity and requiring full mobility . as shown in the embodiment of fig1 , a ribbon cable 38 is used for connecting the sensors 29 , 30 . this is woven as a flat ribbon with closed edges . at roughly the height of the belt 34 , the ribbon cable is incised lengthwise , in order to produce the f - shape by folding over . when a large number of sensors or electrodes need to be connected , it might be difficult to accommodate the many wires as warp threads in one plane , such as occurs in a simple flat strip . for a very large number of connection lines or wires , the structure as in fig9 is especially suitable . in this case , the connection cable 38 consists of a woven tube . such a woven tube is endless in the circumferential direction and forms two imaginary strips 67 , 68 , which are joined together as a single piece along their two margins by spirally running weft threads . in this way , a two - ply formation is created , and connection wires 37 can be accommodated in each layer . the connection wires , in turn , run in the warp direction . at the desired height , the two layers 67 , 68 are separated from each other and folded over , as shown , to produce the desired f - shaped structure . fig1 depicts how not just two outlets 31 , 34 , but more outlets , such as three outlets 31 , 34 , 71 , are possible by means of the striplike cable 38 . in this case , the strip after being woven is separated in the lengthwise direction in the desired manner , parallel to the warp threads , and folded over . according to fig1 , a relatively broad strip 38 , whose overall width when lying flat is as wide as the sum of the widths of the individual branch lines 31 , 34 , 71 , is folded in accordion fashion . this reduces the width of the striplike cable 38 to the width of the broadest branch , for example , branch 31 . furthermore , a “ wiring harness ” can be created in which the individual branch lines 31 , 34 , 71 lead off from different sides . a leading off from the same side , i . e ., an f with three arms , also can be easily achieved . fig1 - 17 illustrate a number of methods for combining the conductor of an insulated wire with a textile backing 73 . an insulated conductor 74 is stripped of its insulation for a distance so that the wire 75 contained inside the conductor 74 is exposed . using sewing thread 76 , the bare piece of wire is sewn onto the electrically nonconductive textile substrate 73 . according to fig1 , the stripped wire 75 is stitched firmly to the backing by means of a thread 76 . in the embodiment of fig1 , the bare wire 75 is secured by means of glue spots 77 . instead of separate glue spots 77 , if the textile substrate contains threads susceptible of hot melt gluing , the stripped wire 75 can also be secured to the substrate by melting these threads to the glue state . the melting can be achieved by heat or by ultrasound . fig1 and 16 illustrate how the stripped wire 75 is sewn as a thread into the substrate 73 . as fig1 reveals , the wire 75 appears alternate on either side of the textile substrate . the textile substrate can be woven , knitted , or nonwoven . the above - mentioned sensors made from elastomer lie flat against the skin and largely seal off this portion of the skin . skin transpiration can only emerge underneath the sensor with difficulty . to improve the aeration and the draining off of sweat , the sensor surface can be structured as shown in fig1 . it can consist , for example , of a plurality of small pyramids 78 whose tips are directed at the skin . under moderate pressure , channels are formed between the tips through which sweat can drain off . beneath the surface shown , the wire 75 used for the contacting can be arranged as in fig1 - 16 , or by using a jacquard technique , as explained by means of fig6 . the elongation sensor as depicted in fig2 consists of an elastomer which is filled with electrically conductive particles . however , hydrogels can also be used as an elongation - dependent sensor . such a sensor contains a hydrogel which is filled with an electrolyte solution . water is stored in a three - dimensional cross - linked matrix of hydrophilic water - insoluble polymers and is virtually immobilized in this way . suitable hydrogels are polymethacrylates , polyphenylpyrrolidones , or polyphenylalcohol . a water - soluble salt is added to the water stored in the hydrogel layer in order to achieve an ionic conductivity for the water . suitable as the salt is agcl , as well as any other physiologically safe metal salt , for example , table salt . a change in cross section caused by a change in length due to stretching or pressure influences the conductivity . the resistance measured is an indication of the strain to which the sensor outfitted with a hydrogel is subjected . the hydrogel is located as a kind of filler between two water - tight and ion - tight , highly elastic layers , similar to that shown for the conductive layer 48 in fig3 . thus , the construction of a sensor based on a hydrogel corresponds to the construction shown in fig3 , using the hydrogel in place of the conductive elastomer 48 . silicone can be used as the elastomer . the benefit of hydrogels is that , depending on the degree of cross linking , one can achieve a very soft texture , conveniently worn on the body . the garment according to the invention has been described in detail in connection with a body suit . the body suit represents the preferred embodiment . however , it is also possible to fasten the indicated sensors on vests , t - shirts , or undershirts , as long as these garments are worn closely against the body . in a body suit , one or two belts which can stretch in the lengthwise direction run transversely to the longitudinal axis of the wearer . elongation measuring strips are arranged in these belts . electrodes for tapping the action currents of the heart or for measuring the skin resistance are located on the outer side of the belts , making contact with the body .
a garment preferably in the form of a body suit which carries one or more sensors for sensing bodily functions of a wearer of the body suit . the body suit preferably has stretchable sections or belts upon which the sensors are carried such that the sensors are maintained in proper position on the body for reliable detection of the body functions .
