ABSTRACT:
Microfluidic valves constructed from elastomeric materials as the valve body components and employing shape memory alloy in wire form as the valve actuator. Various configurations of individual valves having both normally open and normally closed states are described. Apparatus using such valves and providing logic functionality with fluidic logic outputs are discussed. Apparatus that can be used for materials processing at the nano- or micro-scale are presented. Various forms of logical control of valve arrays are explained.
