| piezoelectric effect |
The production of a voltage between opposite sides of a piezoelectric crystal as a result of pressure or twisting. Also the reverse effect which the application of a voltage to opposite sides causes a deformation to occur at the frequency of the applied voltage. (Converts mechanical energy into electrical energy and electrical energy into mechanical energy.)

| piezoelectric effect |
the generation of electric charge by certain materials when a force is applied, or conversely the deformation of the material when a potential is applied. Usually electrodes are deposited or attached to the material to facilitate electrical coupling
