Ultrasonic motors with polymer-based vibrators
IEEE Transactions on Ultrasonics, Ferroelectrics, and Frequency Control, 2015With their characteristics of low density and elastic moduli, polymers are promising materials for making ultrasonic motors (USMs) with high energy density. Although it has been believed for a long time that polymers are too lossy to be applied to high-amplitude vibrators, there are several new polymers that exhibit excellent vibration characteristics.

Press forming using ultrasonic vibration
Journal of Materials Processing Technology, 2007Abstract In press forming, wrinkling and cracking must be avoided in the production of high-quality products. This can be achieved by decreasing the coefficient of friction between the sheet metal and the die. As such, using ultrasonic vibration, which involves wave at frequencies of over 20 kHz, is one way to avoid this unfavorable phenomenon.
