A piezoelectric generator is specified, comprising a deformation body, which spans a projection surface and is embodied with a setpoint pressure surface situated opposite the projection surface, wherein the projection surface can be converted from a smaller projection surface when not loaded under pressure into a larger projection surface when pressure is applied to the setpoint pressure surface substantially perpendicular to the projection surface, and a spring effect is provided which counteracts an application of pressure to the setpoint pressure surface, wherein an electromechanical transducer element comprising a piezoelectric material wholly or partly spans the projection surface, such that the transducer element is embodied in an expandable fashion upon pressure being applied to the deformation body, and electrical microenergy can be generated by means of the piezoelectric material.

The invention relates to a piezoelectric drive, in particular for microvalves. The drive comprises a deformation layer coupled on one side to a piezoelectric layer, which is provided with at least one pair of electrodes, made of two electrodes of opposite polarities, to provide electricity. According to the invention, both electrodes of opposite polarities of the pair of electrodes are arranged together on the side of the piezoelectric layer facing away from the deformation layer. The invention also relates to a microvalve comprising at least one valve channel and a membrane that opens or closes the valve channel, where the membrane simultaneously forms the deformation layer of such a piezoelectric drive.

A device for the emulsification and separation of small amounts of immiscible liquid phases has essentially a cover plate (), which can be tightly connected to a base plate (), where microchannels () in the form of grooves are cut out on the inner surface () of the base plate () and/or cover plate (). In a mixing zone, two microchannels () run in a wave shape crossing one another a number of times. In a subsequent separation zone, they run essentially straight combined in a common microchannel (). The otherwise tightly sealed-off microchannels () can be filled and emptied again via inlet apertures () and outlet apertures ().

A connection coupling forms a line connection for liquid or gaseous substances to microcomponents ( ) in platelet form. A coupling body ( ), which is substantially U-shaped in cross section, accommodates the edge of the plate-like microcomponent ( ) between an upper limb plate ( ), which has the line connection ( ), and a lower limb plate ( ). An edge web ( ) forms a transverse stop for an edge ( ) of the microcomponent ( ). A further stop means, for example a lug ( ), forms a longitudinal stop for positioning of the microcomponents ( ).
