Wearable integrated thermocells based on gel electrolytes use body heat as power source
Electronics integrated into textiles are gaining in popularity: Systems like smartphone displays in a sleeve or sensors to detect physical performance in athletic wear have already been produced. The main problem with these systems tends to be the lack of a comfortable, equally wearable source of power. Scientists are now aiming to obtain the necessary energy from body heat. They have now introduced a flexible, wearable thermocell based on two different gel electrolytes.
