<p>The present invention discloses various embodiments of a thin film fluid control system (10, 110, 220) for controlling fluid flow through tubular conduits (24, 124, 224). The system is designed such that a shape memory alloy (14, 114, 214) is transformed between austenitic and martensitic phases to constrict or open the tubular conduit as desired.</p> |
