Piezoelectric multi-layer component e.g. piezo-ceramic piezo actuator, has base with dielectric thicknesses and inner electrodes, and contact units of porous material running perpendicularly to electrodes

摘要

The component has a base with a stack of superimposed dielectric thicknesses (5) and inner electrodes (3, 4). Electrically conductive contact units (1, 2) run perpendicularly to the electrodes and contain the porous material. Metal thickness are separated from each other by dielectric thicknesses, and are electrically connected with each other by contact units. An electrically conductive layer (12) is arranged on a porous body.
