A solid state motor includes a plurality of piezoelectric elements assembled in a stack. Each element has two opposing planar surfaces. A plurality of electrodes each has a planar section contacting the planar surfaces of two adjacent elements in the stack. A silicone adhesive is adapted to adhere to the piezoelectric elements A plurality of alumina particles are disposed in the silicone adhesive A protective housing cylindrically encases the combination of the stack, electrodes, and silicone adhesive.
