Nature-Inspired Flow Control in Micro-Fluidic Systems Using Integrated Polymer Actuators

摘要：

We propose a novel concept for flow control in micro- fluidic systems, which is inspired by nature, namely micro-organisms that swim through a liquid by beating microscopic hairs, cilia, covering their surface. We have fabricated polymer micro-actuators that resemble the cilia, and we have integrated these in a micro- fluidic channel. Flow visualization experiments show that our micro-actuators can indeed be used for micro-fluidic flow control: they can generate substantial flow velocities and create very efficient mixing flows. Since the micro-actuators can be actively controlled using an electrical signal, they have exciting applications in micro-fluidic devices.
