The idea behind this compact and economical Vibration Sensor Alarm is very simple. It uses a cheap and cheerful vibration sensor to drive a piezo-sounder. As can be seen in the circuit diagram, it is ...

A new energy harvester developed by University of Michigan researchers can harness energy from vibrations and convert it to electricity with five to ten times greater efficiency and power than other ...

Piezo comes from the Greek word “piezein,” which means “squeeze” or “apply some pressure.” Whether they take form as a transducer or sensor, piezo components all operate as the result of some degree ...

Piezoelectric crystals are a class of materials that exhibit a unique property called piezoelectricity. These crystals generate an electrical charge when subjected to mechanical stress or strain, and ...

The high-performance flexible PENG is designed based on branch-heterostructure fiber fillers. By combining signal processing circuit design and machine learning algorithms, a power grid transmission ...
