Xerographic Transfer and Charging by Means of the Piezoelectric Effect
  DOI :  10.2352/J.ImagingSci.Technol.1996.40.4.art00004  Published OnlineJuly 1996

Bending a ferroelectric polymer produces internal polarization that can lead to external electric fields. Both theoretical and experimental analyses have been carried out to predict the magnitudes of these fields, using flexible ferroelectric polymer materials based on polyvinylidenefluoride. The output depends on the thickness of the film, the bending radius, and a measured piezoelectric coefficient that is characteristic of the material. The electric field can exceed the levels now used in xerographic transfer and charging subsystems, suggesting that piezoelectric bending could replace conventional high-voltage power supplies and corona devices. Examples of applications to copier and printer subsystems are described.
