Abstract

A microfluidic device may include a substrate having a cavity therein, and a bendable membrane within the cavity and having a plurality of spaced apart valve passageways therein. The bendable membrane may be bendable between a first position with the valve passageways being opened, and a second position with the valve passageways being closed. The microfluidic device may further include an actuator configured to bend the bendable membrane between the first and second positions.
