Summary edit

Description
English: Principle of piezoelectricity:
  • sensor: when the crystal is pressed, the barycenter of negative charges is different from the barycenter of positive charges;
  • actuator: when a voltage is applied, the barycenters are pulled away, creating a deformation.
Français : Principe de la piézoélectricité :
  • capteur : lorsque le cristal est comprimé, le barycentre des charges négatives est différent du barycentre des charges positives ;
  • actionneur : lorsqu'une tension est appliquée, les barycentres sont décalés, créant une déformation.
