In many applications, harsh ambient conditions present a significant challenge for sensor technology. In such cases, ultrasonic sensors that are largely unaffected by physical influences become ...

Ultrasonic sensors have been a staple in the sensing space for several decades due to their capabilities, flexibility, and low cost. As the rise of IoT finds its way into virtually every market and ...

Researchers have developed a battery-free sensor that reacts to sound waves, such as particular spoken words, producing enough vibrational energy to power an electronic device. The novel sensor would ...

• A single linear sensor monitors 20 positions. • Time to read 20 positions matches that of a single position. • Strokes over 5,000 mm, accuracy of ±20 μm, and resolutions of 1 μm. It is often ...
