piezoelectricity
Squeeze creates voltage
Piezoelectricity is the property of certain crystals and ceramics to generate an electric charge when mechanically stressed—squeezed, bent, or struck.
The effect works in reverse: apply voltage and the material deforms.
This makes piezoelectric materials useful in devices from microphones and guitar pickups to ultrasound machines and barbecue igniters.
Quartz is the classic example.
