摘要： A micro-mixer (8) is disclosed having at least one mixing point (9, 10) which is connected to an inlet channel arrangement having at least two inlet channels (3, 4) and to an outlet channel arrangement, and a mixing method is disclosed for at least two fluids which are supplied from different directions. With this mixer and method it is intended to achieve a rapid and predeterminable mixing of the fluids. For that purpose, a separating element (5) which extends into a region of the mixing point in which the inlet channels run parallel to one another is provided. By this means the fluids can be kept separate from one another until their flow speeds virtually coincide in respect of value and direction. Only then are they brought into contact with one another.

摘要： A flow system (1) comprising a first part (2) and a second part (3), the parts (2, 3) being made from materials having different coefficients of thermal expansion. The first (2) and second (3) parts are positioned relatively to each other in such a way that when the ambient temperature changes corresponding changes are caused in a flow channel (4) formed in the first part (2), thereby changing the flow resistance of the flow channel (4). Thereby a change in flow resistance caused by a change in viscosity of a fluid being transported by the flow system (1) can be counteracted. The resulting flow resistance of the flow system (1) is thereby at least substantially independent of the ambient temperature. Furthermore, a micro fluidic system comprising the flow system (1). The micro fluidic system may be or form part of a medical device, a fluid analysis system, e.g. a device for measuring blood glucose levels of blood samples, or an infusion device.

摘要： This invention relates to an elastic bandage for supporting a body extremity such as a leg. Such bandages are used to overcome problems with fluid retention and swelling in the legs, occurring as a consequence of varicose veins, vascular incompetence, pregnancy, etc. It is a task of this invention to supply an active support for a body extremity such as a leg, which can be used by a person underneath the clothes and will not reduce the mobility of the patient. This task is solved in that an elastic bandage comprises an elastic layer for surrounding a body extremity to exert compressive force on the extremity, the bandage being, at least partly, formed by elastomeric actuation elements, whereby electrical control of the compressive force is possible, and where the control is due to a signal from some sensing system.

摘要： A miniature actuating device (1), is disclosed, with a carrier (13), a diaphragm (11), a hollow space (15) being formed between the carrier (13) and the diaphragm (11) and an insulating layer (12) being arranged between them, and with two electrode terminals (16, 17) for producing an electrostatic field between the diaphragm and the carrier for an activated state. With an actuating device of this kind, it is desired that the throw that can be achieved under the influence of the electrostatic field be rendered as large as possible. To that end, the hollow space is present only in the state of rest and in the activated state virtually disappears.

摘要： The present invention relates to dielectric actuators or sensors of the kind wherein electrostatic attraction between two electrodes located on an elastomeric body leads to a compression of the body in a first direction and a corresponding extension of the body in a second direction. The dielectric actuator/sensor structure comprises a first sheet of elastomeric material having at least one smooth surface and a second surface and a second sheet of elastomeric material having at least one smooth surface and a second surface. The sheets are laminated together with their second surfaces exposed, and there is provided a first electrode on the second surface of the first sheet and second electrode on the second surface of the second sheet.

摘要： A tubular elastomer actuator with a shape in a cross-sectional view which shape exposes at most one single axis of symmetry of a specific length, e.g. an oval shape. The actuator could be made from a sheet made from a plurality of plate shaped elements which are laminated together and rolled. Each plate shaped element may have a corrugation that gives the element an anisotropic structure, and contains an electrode on only one surface. The actuator displacement is the result of shrinkage displacement of the plate shaped elements upon the application of electrical field across their thickness.
