We all know that wearable devices are only going to become more popular in the upcoming years. Their battery life is always going to be an issue. Some companies are already working on solar wearables. But why not use body heat to charge wearable devices? A team from the Korean Advanced Institute of Science and Technology is working on that very idea. It has designed a flexible generator made of thermoelectric materials:
This is quite a revolutionary approach to design a generator. In so doing, we were able to significantly reduce the weight of our generator, which is an essential element for wearable electronics.
explained team leader Byung Jin Cho. Technology is only going to advance in this area in the upcoming years. Don’t expect your iWatch or next Samsung wearable to be chargeable using your body heat. But we could get there in a few years.
