Design and Evaluation of Tesla Valve for Microfluidic Applications

Abstract

We have designed and evaluated a Tesla valve for microfluidic applications by simulation. The Tesla valve is a non-mechanical check valve structure and is expected to prevent contamination of samples in microchannels significantly. In this study, we succeeded in finding a Tesla valve structure that provides higher performance when applied to a microfluidic channel than the conventional one. In addition to the Tesla valve structure, a check valve structure with a venous valve structure was combined with the Tesla valve structure.
