Outline of Final Research Achievements

In our research, we have aimed to develop an extraordinarily small spherical motor for a blood vessel endoscope. It hasφ3 rotor and a wire-made stators like coils. We applied ultrasonic vibration to the wire from outside to transmit it to drive a rotor. We can control the rotational speed and the rotational by changing ratio of the traveling wave and the standing wave. We have shown to make an experimental mode of endoscope and the enough function successfully.
