Abstract

We report here the design, simulation, fabrication, and characterization of an elastomer-based biomimetic check valve resembling the mechanics of the venous valves in mammalians. Young's modulus of different tones of polydimethylsiloxane (PDMS) elastomer was measured. The one layer soft lithographically fabricated check valve completely blocked the backward flow at a flow rate larger than 200 μL/min. The valve can be easily integrated into elastomer-based microfluidic devices to serve as "diode"-like integrated fluidic components for flow regulation.
