Classification of Microvalves ---- A Review

Abstract

Miniaturization of microvalves is required in many microfluidic applications towards the commercial standards. As examples, the applications of microvalves are flow regulation and on/off switching. Microvalves are primarily divided into active microvalves and passive microvalves according to their working principles. These microvalves may be involved with mechanical systems, non-mechanical systems and external systems.
