Micro ultrasonic motor for endovascular diagnosis and surgery

Research output: Contribution to conferencePaperpeer-review


We present a micro ultrasonic motor having rotary and linear motions for endovascular diagnosis and surgery. The stator prototype is a cube of side 3.5mm, and the main body is fabricated as a single metallic cube with a through-hole at the center. Four piezoelectric elements are bonded to the sides of the stator. When AC voltage is applied to the piezoelectric elements, the circumference of the stator generates elliptical motions. We can obtain the output from a shaft inserted through the hole. We developed the first prototype of the stator, and determined the rotary-linear motion.
