Abstract:
A microvalve system for providing robust and durable operation within a MEMS environment, said microvalve comprising:a valve seat comprised of a substrate material; a diaphragm configured with said valve seat to define a passageway, said diaphragm comprised of said substrate material and having a boss component, said boss component having a protruding portion configured for closure of said passageway when said boss component is in juxtaposition with said valve seat; and an external actuation device being adjacent to said diaphragm and having an internal bias pressure, said external actuation being configured to urge said diaphragm towards said valve seat to regulate flow of fluid within said passageway; and an actuation mechanism for operating said external actuation device based on said bias pressure to facilitate regulation of flow fluid within said passageway.
