Piezoelectric actuators are commonplace electronicdevices, with examples including motors,fans, sound transducers, pumps, vibration controllers,deflection plates, position stabilizers,and active ...

Piezoelectric transducers are commonin ultrasonic and acoustic-alarm-signaling applications. To getenough acoustic power from a piezoelectrictransducer, you must power thedevice with a frequency at or ...

A piezoelectric motor is a linear motor with bidirectional motion. It uses friction to grip the armature while a voltage is ramped to warp the piezoelectric material and move the armature. The voltage ...

MIT has pulled out all the stops in an energy scavenging circuit for piezoelectric power sources. The traditional way to extract power from these is simply to connect a bridge rectifier to the piezo ...

Scientists have developed a new algorithm and circuit technology allowing high-frequency piezoelectric resonators to be used for phase locked loops (PLL). It was confirmed that these operate with low ...

UD engineers are the lead inventors on a new patent for making piezoelectric devices, such as sensors and actuators, using Nodax®, a biodegradable, bio-based polymer. Every year, more than 400 million ...

Custom piezo transducers for OEM's with pre-configured connectors and flexible printed circuit boards (PCBs). These piezo components are designed for easy integration in any application from medical ...

Tunability in lenses typically requires bulky components, but researchers have created a metasurface lens that uses a piezoelectric thin film to change focal length when a small voltage is applied.
