    摘要: A method and a device for position and/or type-selective control of the position and/or change of position of suspended particles in a multielectrode system by the effect of polarization forces that are induced in the particles by alternating electric fields in the multielectrode system, which particles comprise biological or synthetic objects with dimensions essentially corresponding to those of biological cells or cell organelles, viruses or macromolecules, base on the fact that the multielectrode system forms with the particle suspension an electrical network, in which means of resonance are provided for creating a resonant increase or damping of the field strength of the alternating electric fields at certain frequencies in at least one locally demarcated region of the multielectrode system.

    摘要: A dielectric micromechanical element the moveable component of which (hereinafter referred to as rotor) is an electrically homogeneous or inhomogeneous dielectric. The rotor is driven via one or more electric field vectors which are generated via electrode arrangements by switched voltages and/or by triggering the electrodes with phase-shifted voltages. On at least one side of the rotor and/or inside the rotor the electrodes form a linear or curved row of electrodes.

    摘要: A motor whose torque is not generated by magnetic fields but rather by dielectric forces to be used in microelectronics and micromechanics. The rotors are composed of several dielectrics, which are arranged in a sector-shaped or shell-shaped manner or partially or completely envelop each other. These motors can be miniaturized down to a size of a few millimeters. They are distinguished by having slow to medium rotation speeds, short starting phases (ms range and less), extremely low current consumption, simple construction, high running constancy and being practically maintenance free. The characteristic curve of rotation (rotation as the function of the field frequency) may be selected in many ranges by changing the dielectrics of the rotor.

    摘要: The present invention relates to a dielectric motor which is driven by means of electric fields. The motor is distinguished by two or more dielectric rotors being disposed in a central region which is surrounded by several electrodes.The rotors may be made of different dielectric materials and be electrically axially asymmetric in design. They are driven by continuously or discontinuously rotating electric fields. Depending on the geometric and electric design, very variable rotation conditions can be achieved, which can be simply controlled via the frequency of the rotating fields. The motor is suited for switch and drive purposes and can be utilized to construct microdosing devices, pumps and valves.

    摘要: For the fixated cryopreservation of single living biological objects or s objects compiled in a given number (for example cells) a cryogenically cooled substrate (13) is jetted therewith in a enveloping solution in microdroplet form (12) from a storage vessel, for example by means of a microdroplet jetting device (11). The substrate is temperature-controlled via a coolant (15), the surface to be jetted being located in a gas atmosphere or in vacuum (14). The substrate surface is maintained at a temperature T1 resulting in freezing of the impinging microdroplet, the substrate surface being possibly supportingly microstructured and comprising sensing elements. By controlled movement of either the substrate or the microdroplet jetting device the microdroplets can be applied singly and in patterns in arrays freely selectable or predetermined by the structuring of the substrate. The substrate with the applied microdroplets and the cells frozen therein are stored and/or processed by a processing means (17) ablating the material or applying said material at temperatures T2 of down to -273.degree. C. In the cryogenic condition manipulations such as removal by mechanical ablation or addition of solutions or substances to the surface of the substrate can be undertaken. During thawing the substrate surface is brought to a temperature T1 above the freezing point of the enveloping solution and the microdroplet array thawed in a predefined manner.
