In this sense, the application range of 1-3 piezoelectric composites is wide, e.g., transducers for medical ultrasound 23, sensors 24, 25, and harvesting energy 26. There are numerous studies on the ...

Nanoscale luminescent force sensors excel at measuring piconewton forces, while larger sensors have proven powerful in probing micronewton forces. However, large gaps remain in the force ...

As an example, [Circuit Valley] has an IKEA Vallhorn motion sensor for a teardown, it’s as you might expect, a passive infrared sensor (PIR) sensor coupled with a Zigbee interface. Inside the ...

The collected evidence supports the premise of in-ear sensors as an innovative and unobtrusive way for physiological monitoring during daily-life and physical activity, but further research and ...
