The University of Tokyo has created a thermo-mechanical micromachine that can sense terahertz electromagnetic radiation, without the need for cryogenic cooling. THz cameras is a possible application. The device is a beam suspended across a gap, coated with a resistive nickel-chromium (NiCr) film. The film absorbs THz radiation, that transfers as heat to the beam, ...
