Abstract
A single-piece multiple electrode conductor for a piezoelectric solid state motor stack with piezoelectric disks arranged with a plurality of electrodes. When the electrodes are connected to and biased by a source of electrical potential, an axial displacement is produced between opposite end surfaces of the stack. The single-piece multiple electrode conductor has a spine member for conducting an electrical potential to the piezoelectric disks. Extending from the spine member are a plurality of rib portions which conduct electrical potential to the piezoelectric disks which form the piezoelectric stack.
