Abstract
Microfabricated microvalves may be used with liquid-filled control channels and actuated using compact and battery-powered components, without the need for heavier or fixed infrastructure. The disclosed embodiments include microvalves with on-off fluid control with relatively fast response times, coordinated switching of multiple valves, and operation of a biological (enzyme-substrate) assay in a handheld configuration.
