Piezoelectric Energy Harvesting

Piezoelectric energy harvesting converts mechanical energy from vibrations, pressure or motion into electrical energy using piezoelectric materials.

It can power small sensors and devices from ambient mechanical energy.

The Piezoelectric Effect

Piezoelectric materials generate an electric charge when mechanically stressed. By placing these materials where vibration, footsteps or pressure occur, the resulting voltage can be captured, conditioned and stored.

It is ideal for self-powered wireless sensors, wearable electronics and energy-harvesting floors, though the power output is small.
