A study demonstrates how the human hand can act as a powerless infrared radiation source in encryption/decryption and signal generation applications. Infrared emitters are used to interface with ...

An optical/electric dual-mode photodetector array for human–machine collaborative infrared imaging was demonstrated. The responsivity of the photothermoelectric photodetector was improved by the ...

Researchers have developed a soft artificial retina that helped blind mice respond to near-infrared light, a type of light normally invisible to mammals. The device sits on the surface of the ...
