30 results about "Piezoelectric coefficient" patented technology

Piezoelectric coefficient or Piezoelectric Modulus, aka D₃₃, quantifies the volume change when a piezoelectric material is subject to an electric field, or the polarization on application of a stress: d=P/σ where P is polarization, and σ is the stress. There are actually many Piezoelectric coefficients: Dxy. See Piezoelectricity § Mechanism.
