This model shows the conversion of electricity to mechanical motion. Users can pull the slider to change the voltage and observe the change of the crystal. The bottom of the slider corresponds to zero voltage.
The piezoelectric effect is the conversion between electricity and mechanical motion. Mechanical forces on piezoelectric materials can produce electricity (e.g., piezoelectric sparkers). Conversely, applying voltage on some piezoelectric materials results in distortion or deformation. For example, piezoelectric ceramic materials have been used to move the tip of a scanning tunneling microscope (STM).
