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.

The effect of ultrasonic vibration on the compaction characteristics of paracetamol
Journal of Pharmaceutical Sciences, 2000An ultrasonic (US) compaction rig has been developed that is capable of providing compaction pressure together with high-power ultrasonic vibrations of 20 kHz to a powder or granular material in a die. The rig has been used to investigate the effect of US on the compaction properties of paracetamol, a drug that produces tablets that are weak and ...

Microknife using ultrasonic vibration
MHS2000. Proceedings of 2000 International Symposium on Micromechatronics and Human Science (Cat. No.00TH8530), 2002The purpose of this research is to develop a minute size knife for cutting of minute objects such as cells. We report on a microknife that cuts the object by using ultrasonic vibration of a sharp needle. We employed a multilayer piezoelectric actuator for generating the ultrasonic vibration for cutting. Also, we made a tactile sensor for the microknife

Emulsion Polymerization with Ultrasonic Vibration
Journal of Applied Physics, 1950Emulsion-type polymerization reactions have been accelerated by irradiation with ultrasonic energy. A magnetostriction oscillator at 15 kc gave essentially the same results as a piezoelectric oscillator at 500 kc. The rate of formation of polystyrene was doubled and higher final yields obtained using about 0.03 watt of vibrational power ...
