(This sets the minimum open circuit voltage of the piezo at the source vibration frequency and minimum acceleration.) There are also physical practicalities such as the amount of area that can be ...

The piezoelectric effect is an extraordinarily useful and versatile phenomenon which engineers have adapted to countless transducer applications. In some of these, the applied voltage is transformed ...

Piezoelectric motors are increasingly popular for linear motion, but the design of the accompanying drivers is very different from those used by traditional electromagnetic motors. Employing the ...

A 1-op-amp circuit for processing the signal from a piezoelectric accelerometer. Accelerometers are used in instrumentation applications to measure a change in velocity with respect to time or an ...

The humble piezo disc buzzer is much more than something that makes tinny beeps in retro electronic equipment, it can also be used as a sensor. Tapping a piezo buzzer gives an interesting waveform, ...
