Ambient 'T-rays' could help power IoT devices
2020-06-30
Most things with a measurable temperature – human beings going about their daily routines, inert objects – generate terahertz waves, radiation that is sandwiched between infrared and microwave on the electromagnetic spectrum. So far, these waves haven’t proved very useful, but now scientists at MIT are trying to harness them with devices that use them to generate electricity that could charge the ...
