Electrodes pour dispositif piézoélectrique.

摘要

The piezoelectric device has at least two electrodes (10,20). The electrodes (10,20) are separated by a piezo-electric material (30). Each electrode has a transverse plate (10). One of the electrodes has n longitudinal plates (11) soldered to the transverse plate (10) at an angle (alpha) to it. n is at least equal to one. The other electrode(s) comprise m longitudinal plates (21) soldered to the transverse plate (10) at an angle (alpha2) to it, where m is at least equal to 2. The arrangement of these longitudinal plates (11,21) is such that the first longitudinal plates (11) overlap between the second plates (21).
