Researchers at the Columbia University School of Engineering and Applied Science have invented ‘all-optical’ nanoscale sensors of force that change intensity or color when you push or pull on ...

A tactile sensor based on an optical fibre ring resonator helps blind or partially sighted people interact seamlessly with ...

A new sensor can determine how much rebab is actually needed. Injury rehabilitation can be a bit of a guessing game. Too much exercise can impede recovery, but so can too little exercise. So the ...

I first encountered Spectricity’s tiny S1 sensor at CES 2023, and at the time, the firm had ambitions to introduce it into phones during 2024 and at higher volumes in 2025. This hasn’t played ...

The result is a much better understanding of depth information. The actual sensor is extremely small, but to demonstrate its capability, the company built it into a camera to showcase just how ...

In a groundbreaking study, researchers have created new nanoscale force sensors using luminescent nanocrystals. These “all-optical” sensors change their intensity and color in response to mechanical ...

Two independent teams in the US have demonstrated the potential of using the optical properties of nanocrystals to create ...
