Abstract
A piezoelectric solid state motor includes first and second solderless connectors for connecting first and second chain electrodes, respectively, to a power supply connector. The first and second chain electrodes are interleaved with a plurality of piezoelectric disks, such that the motor expands in an axial direction when a driving potential is applied to the solderless connectors. Each solderless connector comprises a first planar member formed of an electrically conductive material, for placement in electrical communication with one of the first and second chain electrodes, and a second planar member formed integrally with the first planar member for placement in electrical communication with the power supply connector.
