Thermoelectric generator without temperature difference and related measurement technologies

We are developing a thermoelectric generator without temperature difference. It is a three-layer structure of an anode, a colloidal solvent containing nanoparticles (NPs), and a cathode. We also are developing a NPs manufacturing method which is called the laser-induced nucleation method using a femtosecond laser. Three kind of related measurement technologies will be introduced in this paper: (1) the non-scanning white light interferometry for the measurement of the gap between an anode and a cathode, (2) image processing technology from the transmission electron microscope images for the size distribution of sub10 nm-NPs, and (3) the color information from local surface plasmon resonance (LSPR) as an end monitor.
