Important! If you cannot launch anything from this database, please follow the step-by-step instructions on the software page.

Please Note: Many models are linked to directly from within the database. When an activity employs our scripting language, Pedagogica, as do some of the "guided" activities, the initial download may take several minutes. Subsequent activities will not take a long time. See this page for further instructions.

Overview and Learning Objectives

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.

Central Concepts

Key Concept:

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).
