摘要: A bi-directional electrostatic microvalve includes a membrane electrode that is controlled by application of voltage to fixed electrodes disposed on either side of the membrane electrode. Dielectric insulating layers separate the electrodes. One of the fixed electrodes defines a microcavity. Microfluidic channels formed into the electrodes provide fluid to the microcavity. A central pad defined in the microcavity places a portion of the second electrode close to the membrane electrode to provide a quick actuation while the microcavity reduces film squeezing pressure of the membrane electrode. In preferred embodiment microvalves, low surface energy and low surface charge trapping coatings, such as fluorocarbon films made from cross-linked carbon di-fluoride monomers or surface monolayers made from fluorocarbon terminated silanol compounds coatings coat the electrode low bulk charge trapping dielectric layers limit charge trapping and other problems and increase device lifetime operation.

摘要: A method of bonding layers to form a structure, comprises curing a first adhesive while squeezing a first layer and a multilayer structure together between a first backing and a second backing. The multilayer structure comprises a substrate and a second layer, and the first adhesive is between and in contact with the first layer and the second layer. Furthermore, the first layer and the second layer each have a thickness of at most 100 μm, and at least one of the first backing and the second backing comprises a first elastic polymer.

摘要: A microcombustor which is submillimetric in critical dimensions. The invention relies upon solving quenching at submillimetric dimensions. Chemical and thermal quenching are inhibited by selection of materials having a low well depth below approximately 40 kCal/mole. This allows formation of a microcombustor having submillimetric combustion chamber. A preferred microcombustor is formed in a substrate structure. The preferred microcombustor includes a wafer stack of at least three wafers, a central wafer housing a combustion chamber. At least one inlet and outlet are included for the insertion of reactants and exhaust of a flame.
