Piezoelectric materials are used in numerous applications.

The direct piezoelectric effect is used in e.g.

The indirect piezoelctric effect is used in e.g.

A combination of the direct and the indirect piezoelectric effect is found in

  • Vibration Control (e.g. active damping)
  • Smart Structures (e.g. active shape control)
  • Voltage Transformers
  • Quartz Oscillators (e.g. for timing in microelectronics)
