Abstract
A distribution network of electric signals in a piezoelectric or ultrasonic waves motor, is produced by depositing electrodes of conductive material on one face of a strip in dielectric material, that on the other face of the strip conductive tracks are deposited according to an interconnection diagram, designed beforehand to supply the piezoelectric elements with proper voltage. Drillings are made through the strip between the conductive tracks and the electrodes, and through plating or deposit of conducting material, these drillings are made conductive.
