ABSTRACT:
An improved microvalve is described. The microvalve is formed such that the walls of the microvalve are formed from a gel material. Typically, the microvalve includes open flow paths, often holes, through a gel layer. An electric field is applied in regions where fluid flow is undesirable. The electric field compresses the gel closing the flow path thereby preventing further fluid flow.
