Piezo materials are materials that will generate an electric charge when they are deformed, or conversely, they will deform when electrically charged. The latter is the inverse piezoelectric response and the response responsible for actuation.

Applications for piezo actuators include fiber modulation for communications, precise positioning devices, proportioning valves, electrical switches, micro pumps, ink jet printers, and anti-vibration devices.
