Are you always cold? Or always hot? And even better, as the outside temperature adjusts, the patch does as well.Developers say the mobile temperature system is also designed to be comfortable to wear, as it is lightweight and flexible, and is made out of thermoelectric alloys, which use an electric current to create temperature. The engineers estimate that in the summer, it could cut cooling costs by 70%.However, this is all still a few years away at least. "We've solved the fundamental problems, now we're tackling the big engineering issues – the electronics, hardware, and developing a mobile app to control the temperature," explains Renkun Chen, a professor of mechanical and aerospace engineering at the university.
