FPGA embedded system for ultrasound particle manipulation with Sonotweezers

Recent research in acoustic tweezing has mainly focused on the behaviour of devices for specific applications and the fundamental theories of the forces exerted on the target particles. However, compared to optical tweezers, there have been only limited reports about developments and applications of acoustic tweezers at the system level. This paper outlines a novel design of a multichannel electronics system for ultrasonic particle manipulation applications. The development process of this 16-channel embedded-FPGA ultrasonic signal generation system is described and experimental results are presented based on its use with array-based acoustic tweezing devices (Sonotweezers).
