Robots are becoming increasingly capable in vision and movement, yet touch remains one of their major weaknesses. Now, ...

For example, a 2-kN force properly applied to a cubic-centimetersized quartz crystal produces over 12.5 kV. Voltage created by an applied stress is called piezoelectricity. Unlike strain gages that ...

On Aug. 31, 2012, a giant prominence on the sun erupted, sending out particles and a shock wave that traveled near Earth. This event may have been one of the causes of a third radiation belt that ...

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' ...

Evaluating tribological properties such as friction coefficients, friction forces, and torques for arbitrary material pairs, with high precision is crucial for multiple areas of research and industry.

How to create an application-optimized thin force sensor. How the sensor was integrated with a standard RFID IC. The various tests run for accuracy and range under different scenarios. Some ...

New York, NY—January 1, 2025—Mechanical force is an essential feature for many physical and biological processes. Remote measurement of mechanical signals with high sensitivity and spatial resolution ...
