Microvalve
A microvalve is microscale valve, i.e. a Microfluidics, microfluidic two-port component that regulates the flow between two fluidic ports. Microvalves are basic components in microfluidic devices, such as Lab-on-a-chip, Labs-on-a-chip, where they are used to control the fluidic transport. During the period 1995-2005, a lot of Microelectromechanical systems-based microvalves were developed. Microvalves found today can be roughly categorized as ''active'' microvalves and ''passive'' microvalves. Based on the medium they control, microvalves can be divided into gas microvalves and liquid microvalves. Based on their initial mode, microvalves can be divided into normally open, normally closed and bistable microvalves. Types of microvalves Active microvalves Active mechanical microvalves consist of mechanically movable membrane or boss structure, coupled to an actuation method, that can close of an orifice, thus blocking the flow path between the inlet and outlet ports.
