piezoelectric effect
Squeeze produces voltage
The piezoelectric effect is the generation of electric charge in certain crystals and ceramics when mechanical pressure is applied.
The effect works in reverse too—applying voltage causes the material to change shape.
This property makes piezoelectric materials useful in microphones, speakers, quartz watches, and ultrasound devices.
Guitar pickups rely on the piezoelectric effect to convert string vibrations into electrical signals.
