Description

Non-contact manipulation of particles has been studied experimentally using radiation force of ultrasound. A multi-electrode transducer used in the present experiment was a rectangle 20 x 40 mm in size with fifteen electrodes of 20 x 2 mm. Driving a series of electrodes of the transducer with continuos sinusoidal wave of 2.1 MHz, alumina particles were trapped at the nodes of sound pressure in a standing wave field generated between this transducer and a reflector set parallel at 30 mm apart from the transducer. They were transported laterally by changing the driving electrodes sequentially. When a series of a few electrodes were driven, it was possible to move particles stably, and the resolution of moving distance of particles was determined by the electrode interval. Moreover, continuous changes of position of particles could be achieved by shifting the phase between two neighboring electrodes.
