Micro linear ultrasonic motor

Miniature linear ultrasonic motors are required in the variety of filed such as camera devices. Conventional miniature linear ultrasonic motors are long in the drive direction and are not suitable for thin devices such as smartphones. In this research, we have succeeded in generating more than 20 mN of thrust with a motor of about 2 mm in size, and have realized a linear motor that is smaller and has higher output than before.
