piezoelectricity

Examples of piezoelectricity in the following topics:

• Properties of Quartz and Glass

  • Glass is a non-crystalline solid material made of silica, while quartz is a crystalline silicate mineral with piezoelectric properties.
  • Quartz crystals have piezoelectric properties.
  • Piezoelectricity is the ability to develop an electric potential upon the application of mechanical stress.
  • Today, a crystal oscillator is a common piezoelectric use for quartz: the vibration frequency of the crystal is used to generate an electrical signal of very precise frequency.

• Bone Remodeling

  • It has been hypothesized that this is a result of bone's piezoelectric properties, which cause bone to generate small electrical potentials under stress.
