Researchers have created a microphone so thin it looks like a human hair, yet tough enough to survive temperatures as high as 1,000°C. Made entirely from silica glass, this tiny device can detect ...

Ultrasonic sensors measure the distance between a target and the sensor using high-frequency sound waves that are inaudible to humans. The process is simple: the sensor emits ultrasonic waves, which ...

There is a lot of buzz about electromagnetic (EM) detection and ranging sensor technology, which encompass radar, lidar, infrared (IR), ultra-wide bandwidth (UWB), and many others. However, there are ...
