Heavy Particle Collection by Ultrasonic Actuator

摘要：

This paper presents a new method to collect heavy particles by the ultrasonic actuator with two tapered metal strips. Heavy particles, such as medicine pills, can be trapped and transported in air by the actuator. We define the particle with a mass larger than 10 milli-grams as heavy particle. A physical model is developed to explain the trapping mechanism. Effects of driving frequency, input voltage, particle size and weight, and structure of the actuator on the trapping capability are experimentally investigated.
