pyroelectric

Encyclopedia

  • Pyroelectric charge in minerals develops on the opposite faces of asymmetric crystals. The total pyroelectric coefficient measured at constant stress is the sum of the pyroelectric coefficients at constant strain (primary pyroelectric effect) and the piezoelectric contribution from thermal. — “Pyroelectricity - Wikipedia, the free encyclopedia”, en.wikipedia.org
  • The scientists used a pyroelectric crystal heated from −34 to 7 °C (−29 to 45 °F), combined with a tungsten needle to produce an electric field of about 25 gigavolts per meter to ionize and accelerate deuterium nuclei into an erbium deuteride target. — “Pyroelectric fusion - Wikipedia, the free encyclopedia”, en.wikipedia.org
  • Of these 20 piezoelectric crystal classes, 10 of them are pyroelectric (polar). Any material develops a dielectric polarization when an electric field is applied, but a substance which has such a natural charge separation even in the absence of a field is called a polar material. — “Pyroelectric crystal - Wikipedia, the free encyclopedia”, en.wikipedia.org
