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 ...

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 ...

The sensor operates by beaming ultrasonic sound waves through the material from one side and measuring the intensity of the sound detected on the other side. Technically speaking, double-sheet ...

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 ...

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 ...

Dr. Park Chan Wook (Postdoctoral Researcher, Non-Destructive Metrology Group, KRISS); The Korea Research Institute of Standards and Science (KRISS, President Lee Ho-seong) has developed an ultrasonic ...

A sensor has been developed that can detect structural defects in real-time even in challenging environments such as high-temperature pipes in nuclear power plants, hazardous chemical storage tanks, ...

But, similar bursts from other sensors in close proximity may interfere with the echo timing. When that happens, the sensors suffer from a condition called cross talk. Interference from cross talk ...
