So we're going to do exactly what we did in the video with the other guy, so the wireless signal is going through, it's touching Zach's body, and it's reflecting back to the device, and we want to monitor his breathing, his inhale-exhale motion.
On va donc faire exactement ce qu'on a fait dans la vidéo. Le signal sans fil est envoyé, touche le corps de Zach, puis revient vers l'appareil. On veut observer les mouvements de ses inspirations et de ses expirations.
