A new way to harvest electricity from body heat could inspire new wearable devices that never need to be plugged in. The millivolts of electricity this thermoelectric technology produces mandates slim power usage from any electronics plugged in to its feed. However, the developers say there already are fitness trackers and medical monitors today that could work within their device’s power envelope. The new, wearable thermoelectric generator is also sourced from non-toxic and non-allergenic substances, making it a viable candidate for wearable technology.
Made with cotton, this generator harvests body heat to power wearable electronics.
