Researchers at CU Boulder have developed a wearable which is able to draw power from the users body which means there might be a day when we no longer need to plug in wearables to ever charge them again.
According to the source, the new wearable is a low-cost accessory that can be worn as a ring or a bracelet with direct contact with the skin. This stretchable accessory makes use of the heat generated from the human body. More accurately, it converts the internal temperature of a human body into electricity using tiny thermoelectric generators.
According to Jianliang Xiao, the Associate Professor in the Paul M. Rady Department of Mechanical Engineering at CU Boulder, “In the future, we want to be able to power your wearable electronics without having to include a battery.” The new wearable will be able to generate 1 volt of energy for every square centimetre of skin space. Although this is less energy than a regular cell would provide, it would be enough to power a wearable.
It is able to repair itself if damaged and is 100% recyclable as well and is a very good alternative to conventional electronics. Xiao added, “Whenever you use a battery, you’re depleting that battery and will, eventually, need to replace it. The nice thing about our thermoelectric device is that you can wear it, and it provides you with constant power.”
