The chip could also use thermoelectric materials, which produce an electric current when exposed to two different temperatures-such as body heat and the (usually) cooler air around us.
The driving chip DRV592 drove the semiconductor cooler linearly, and the algorithm of fuzzy self-tuning PID was adopted to improve the precision of controlling temperature.
