Hot stuff: schematic of the bolometer showing the graphene sheet in blue. (Courtesy: MIT) A new graphene-based bolometer has been created by Dmitri Efetov and colleagues at the Massachusetts Institute ...

Chip-level future: an artist’s impression of how microscopic bolometers (in the chip on the right) could sense very weak radiation emitted from qubits (in the chip on the left). (Courtesy: Aleksandr ...

Devices such as digital cameras electronically measure levels of high-energy light, and that's good enough for most of us. Now, however, scientists have developed a mechanical alternative that works ...

Researchers have developed a better bolometer, a device for measuring electromagnetic radiation. The new technology is faster, simpler, and covers more wavelengths. Bolometers, devices that monitor ...

The findings, published in the journal Nature Nanotechnology ("Fast thermal relaxation in cavity-coupled graphene bolometers with a Johnson noise read-out"), could help pave the way toward new kinds ...
