Title:  The BAW Based Ultrasonic Micro/Nano/Molecular Manipulation and Its Application

Abstrat:Ultrasonic micro/nano manipulation and fabrication is a promising actuation technology, which employs the nonlinear and linear effects of ultrasonic vibration in fluid, solid and gas to implement the manipulation and fabrication of micro/nano scale materials. The nonlinear and linear effects of ultrasound utilized in this technology include the acoustic radiation pressure, acoustic streaming, acoustic cavitation, ultrasonic vibration velocity, sound pressure, etc. It has potential applications in biomedical sample treatment, micro/nano fabrication process and chemical reaction catalysis. In this lecture, the bulk acoustic wave (BAW) based micro/nano concentration (enrichment), micro/nano tweezers, nano motors, PM 2.5 sampling from air, removal of micro/nano particles, gas-molecule-drive derived catalysis effect for the gas-solid interface reaction, and nano gas/strain sensor fabrication, which have been proposed and developed by the speaker’s group in recently years, are presented. The structures, working principles and characteristics of the ultrasonic devices in these works are demonstrated. The experimental and theoretical work implemented by the speaker’s group, shows that the BAW based ultrasonic methods provide a promising way to handle micro/nano scale samples, to construct high-performance gas sensing systems, and to fabricate high-performance nano-devices.
