Terahertz waves are pervasive in our daily lives, and if harnessed, their concentrated power could potentially serve as an alternate energy source. Imagine, for instance, a cellphone add-on that passively soaks up ambient T-rays and uses their energy to charge your phone.

Energy-harvesting design aims to turn high-frequency electromagnetic waves into usable power

Device for harnessing terahertz radiation might help power some portable electronics.

With a new technique, MIT researchers can peel and stack thin films of metal oxides — chemical compounds that can be designed to have unique magnetic and electronic properties. The films can be mixed and matched to create multi-functional, flexible electronic devices, such as solar-powered skins and electronic fabrics.
