Early on, building and maintaining self-driving maps was expensive. Crowdsourced techniques make it cheap and allow improved ...

Revolutionary photon-avalanching nanosensors have been developed by researchers at Columbia Engineering, promising to ...

US-based researchers used photon avalanching nanoparticles (ANPs) to build sensors that can measure force over high dynamic ...

Researchers report that they have invented new nanoscale sensors of force. They are luminescent nanocrystals that can change intensity and/or color when you push or pull on them. These 'all-optical' ...

Mechanical force is an essential feature for many physical and biological processes. Remote measurement of mechanical signals ...
