We show that full-image micro-PIV analysis in combination with images of transient particle motion is a powerful tool for experimental studies of acoustic radiation forces and acoustic streaming in microfluidic chambers under piezo-actuation in the MHz range. The measured steady-state motion of both large 5 microm and small 1 microm particles can be understood in terms of the acoustic eigenmode...

Contactless acoustic manipulation of micro/nanoscale particles has attracted considerable attention owing to its near independence the physical and chemical properties targets, making it universally applicable almost all biological systems. Thin-film bulk wave (BAW) resonators operating at gigahertz (GHz) frequencies have been demonstrated generate localized high-speed microvortices through str...

Auditory scene analysis requires the listener to parse the incoming flow of acoustic information into perceptual "streams," such as sentences from a single talker in the midst of background noise. Behavioral and neural data show that the formation of streams is not instantaneous; rather, streaming builds up over time and can be reset by sudden changes in the acoustics of the scene. Here, we inv...
