摘要： A compressed fluid microvalve for controlling flow of compressed fluid from a region of high pressure to a region of low pressure is provided. A chamber includes an inlet port, a region of high pressure, and an outlet port leading to a region of low pressure. A cantilever beam includes a first portion, a second portion, and a third portion. The cantilever beam is anchored to a portion of the chamber and is suspended in the chamber such that the first portion and third portion of the cantilever beam are exposed to the region of high pressure on all sides. The second portion of the cantilever beam overlaps the outlet port. The cantilever beam includes a first position in contact with the outlet port to prevent fluid flow from the chamber through the outlet port and a second position removed from contact with the outlet port to permit fluid flow from the chamber through the outlet port. A controller is in electrical communication with the cantilever beam and is configured to provide an actuation pulse to the cantilever beam to move the cantilever beam from the first position in contact with the outlet port to the second position removed from contact with the outlet port.

摘要： A micro-electromechanical device for controlling compressed fluid flow is provided. A chamber includes a fluid flow inlet port, a high pressure region exceeding 30 bar, and a fluid flow outlet port. A moveable micro-electromechanical valve is positioned to contact the fluid flow outlet port when the moveable micro-electromechanical valve is in a first position. An electrical connection to the moveable micro-electromechanical valve provides an electrical pulse train to the moveable micro-electromechanical valve to actuate the valve at a rate of 10 KHz or more to move the valve in order to control fluid communication between the high pressure region and a low pressure region downstream from the fluid flow outlet port.

摘要： A method produces patterned deposition on a substrate (14) from compressed fluid. A delivery system (12) cooperates with a controlled environment (30, 100, 200) retaining a substrate (14) for receiving precipitated functional material 44 along a fluid delivery path (13) from the delivery system (12). A mask (22) is arranged in close proximity to the substrate (14) for forming the patterned deposition on the substrate (14).
