Soil is often perceived simply as "dirt," but in reality, it is a dynamic, living system that acts as Earth's natural sponge.

Mechanical force is an essential feature for many physical and biological processes. Remote measurement of mechanical signals with high sensitivity and spatial resolution is needed for a wide range of ...

Understanding acoustic feedback in hearing aids. Power consumption challenges in hearing aids. Functionality integration and its impact on energy consumption. The benefits of using photoreflectors for ...

The Optipact motion sensors determine rotational or translational velocities of machinery or products in a wide variety of applications. The sensors are built around an optical system: The velocity of ...

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' ...

Air bubble sensors are used to detect air or gas bubbles in flexible clear plastic tubes. They are intended to prevent air infusions. The air bubble sensor has no contact with the liquid and is ...

A new technical paper titled “Massively parallel and universal approximation of nonlinear functions using diffractive processors” was published by researchers at UCLA. “Nonlinear computation is ...
