Abstract

This paper reports the design, fabrication, and testing of an electrostatically actuated microvalve that is molded in polydimethylsiloxane (PDMS) and fabricated exclusively with soft-lithographic techniques. The valve is composed of a deflecting elastomeric membrane with embedded conducting nanoparticles suspended above a microfluidic channel. Some of our present valve configurations require actuation potentials as low as 20 V, and model-based predictions suggest lower potentials are accessible with proper process controls.
