Research Summary

Ren Research Image

Autonomous micromotors that mimic living micro-organisms are of growing interest because they could be able to carry out many challenging tasks in human body, such as precise drug delivery, cell manipulation and micro-surgery. Among many kinds of autonomously powered micromotors, acoustically-driven ones are especially attractive because they do not require chemical fuel and operate at low tissue-friendly acoustic power. My current project is focused on studying the behavior of  acoustically-driven motors in microfluidic channels, including the directional movement in standing acoustic wave fields and highly polarized collective behavior.
