    摘要: Disclosed is a process for manipulating microscopic dielectric particles in which particles are exposed to an electric field. In disadvantaged processes the particles are exposed to inhomogeneous electric field and are polarized by them. The polarized particles are moved in the direction of higher field strength. These processes permit no reversal of the traveling direction of the particles. The particles are enriched at the electrode so that they cannot be retained in free space. In the invented process the particles are exposed to high-frequency field traveling in one or more prescribed direction, by which the particles are subject to a force which sets them in a motion that is strongly synchronous to the field. With the aid of a device for carrying out the invented process, the particles can be manipulated very flexibly. By means of linearly or circularly disposed electrodes, the particles can be moved on linear paths in any direction including through branched microstructures, they can be separated according to their dielectric properties and retained without contact. Applications are in the fields of biotechnology and molecular separation, focussing and microtransport technology.

    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 device for amperometric adjustment of an ion concentration in an adjustment solution comprises at least three chamber-shaped electrolyte regions, each with a control electrode and diffusion depressant means and which can be filled with electrolytes, whereby all electrolyte regions can be brought into contact with the adjustment solution in such a way that, when current flows through the control electrodes, ions can be transported from the electrolyte solutions through the diffusion depressant means into the adjustment solution or in the reverse direction, and means for supplying each electrolyte region with control currents. The device is designed for adjusting the pH value and/or an ion concentration of the adjustment solution different to the hydrogen ion concentration. At least two or all electrolyte regions are supported by a joint holding means.

    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.
