While learning about different types of vibration sensors for condition monitoring, I came across a cheap piezoelectric shock/tap/vibration sensor switch module hiding in a corner of my messy ...

A typical piezoelectric sensor comprises a disk of PZT-5A ceramic material with metallized electrodes on its surfaces. Applying electrically conductive epoxy to the electrodes connects external wiring ...

Flexible piezoelectric sensors are essential to monitor the motions of both humans and humanoid robots. However, existing designs are either are costly or have limited sensitivity. In a recent study, ...

Sensor applications are one of the most logical places to use nanomaterials: the two key features for a sensor are its precision and its size, two areas where nanomaterials can provide big gains.

A piezoelectric harvesting device fabricated by mems technology has, for the first time, generated a record of 85µW electrical power from vibrations. A wafer level packaging method was developed for ...
