Abstract
We present a concept for and experimental demonstration of an active microfluidic mixer that uses microvalves to control periodic flow deviation. This active design allows the degree of mixing to be varied independently of flow rate. The mixer is compact and efficient, achieving mixing of different fluids through chaotic advection by stretching and folding the interface of the fluids.
