(Nanowerk Spotlight) For decades, researchers have sought to understand and harness the pyroelectric effect in biological materials. Pyroelectricity refers to the phenomenon where heating or cooling a ...

Electrical engineers at Duke University have demonstrated the fastest pyroelectric photodetector to date that works by absorbing heat generated by incoming light. Capable of capturing light from the ...

Metasurfaces featuring tailored silver nanocubes could allow thermal photodetectors to approach speeds akin to traditional digital cameras. (Nanowerk News) Electrical engineers at Duke University have ...

The metasurface is an ultra-thin resonant element with special physical properties. A good example of such an innovation is seen in the thermally based photon-detector project at Duke University, ...

Pyroelectric materials are able to convert any incident radiation into a signal, allowing them to sense wavelengths from UV through to THz. DLaTGS in particular is very sensitive, meaning a higher ...

MIT engineers have developed a technique to grow and peel ultrathin “skins” of electronic material. The method could pave the way for new classes of electronic devices, such as ultrathin wearable ...
