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 ...

The HC-SR04 ultrasonic range sensor is a pretty cool pre-wired module that you actually enjoy using when you start playing with electronics, microcontrollers, and robotics. As you might have noticed, ...

Technical systems must be regularly checked for defects, such as cracks. Up to now, piezo sensors measuring pressure, force or voltage have been used to reliably detect such faults – but only to ...

Piezoelectric micromachined ultrasonic transducers (PMUTs) harness the direct and inverse piezoelectric effects in thin-film materials deposited on micromachined silicon substrates to generate and ...

Throughout the surgical process, the surgeon must have access to a real-time assessment of blood vessels to make evaluations relative to the flow of blood. Piezo transducers are at the heart of ...
