Piezoelectric Generator 27mm Piezo Sensor Buzzer
Generate electricity from sound and pressure

Description:

Piezoelectric sensors use quartz crystals to produce sound using an electrical energy. The crystal expands and contracts when a voltage is applied creating sound frequency. It also has the ability to work in reverse; pressure and sound distort the shape of the quarts crystal creating and electrical energy. The electrical energy can be stored and harnessed in batteries and capacitors. 

Features:

· High sound output/input
· DIY applications
· Musical instrument sensors
