    Abstract: An implantable beneficial agent infusion device (1) featuring a unique energy recovery circuit (37) and a deflectable energy storing member such as a piezo-electric membrane (21) is disclosed. The circuit and deflectable energy storing member cooperate to permit electrical energy employed to activate the member to be at least partially recovered. In a preferred embodiment, the deflectable energy storing member is connected to a seal (22) which is opened to permit the delivery or infusion of a pre-determined amount of a beneficial agent to a patient when the member is deflected or actuated through the application of a sufficiently high voltage thereacross. Charge stored on or in the deflectable energy storing member as a result of the voltage being applied thereacross is recovered by a novel circuit when the deflectable energy storing membrane is permitted to return to its non-actuated state or position.

    Abstract: The invention relates to an electro-mechanical component (10), consisting of a polymer body (12) which has a mechanically active part containing a spring (14a, 14b) and a frame (18) and of a metallic layer (30) which encompasses the springs in a substantially complete manner, in order to mechanically stabilise the latter. The electro-mechanical component can be an acceleration sensor, a rotational speed sensor, a microvalve, a micropump, a pressure sensor or a force sensor. In comparison to electro-mechanical components which are produced by silicon technology, the electro-mechanical component allows a drastic reduction in the cost of its production, as simple injection moulding and/or stamping technology can be used in place of the expensive silicon technology.

    Abstract: A micromachined fluid control apparatus includes a micromachined boiler (52) with a thermally conductive housing that has a housing exterior surface and a housing interior surface. The housing interior surface defines an interior void that has a fluid (62) positioned within it. A heat source (54) is incorporated with the housing exterior surface. The heat source (54) selectively generates heat that is conducted through the thermally conductive housing so as to selectively expand the fluid (62) in a predetermined manner. A load resistor (64) may be positioned within the thermally conductive housing. Current may be driven through the load resistor (64) in a predetermined manner to further control the selective expansion of the fluid (62).

    Abstract: A microvalve for regulating a fluid flow has a valve base body (10) with a valve opening (12; 40) and a sealing edge, and a valve plate (14) with fluid passages (16; 60). The valve plate (14) is movable in the perpendicular direction in relation to the valve base body (10), so that in a first position the valve plate (14) closes the valve opening (12; 40) and in a second position it is vertically spaced away from the valve opening (12; 40), defining a cross-section of flow through the valve opening (12; 40) and the valve plate (14) determined by the distance between the sealing edge and the valve plate (14). The contour of the sealing edge (42) of the valve opening (12; 40) is selected in such a way that the sealing edge (42) is longer than the sealing edge (39) of a square-shaped valve opening of the same surface area.
