electrostrictive

electrostrictive

Materials that change in size in response to an electric field and produce electricity when stretched are called electrostrictive. These materials are primarily used as precision control systems such as vibration control and acoustic regulation systems in engineering, vibration damping in floor systems, and dynamic loading in building construction.
