Abstract: An arrangement for mechanically changing a surface includes an insulating layer, a pair of electrodes, which is arranged on or in the insulating layer, and a piezo element, which is arranged on or in the insulating layer. The piezo element is separated from the pair of electrodes by the insulating layer. The pair of electrodes is designed to generate in a region of the piezo element an electric field, which causes the piezo element to carry out a mechanical change of shape, in order in this way to mechanically change a surface of the arrangement. The pair of electrodes is also designed to generate the electric field such that the electric field has a minimum field strength in a surrounding area of the arrangement, in order in this way to generate a plasma in the surrounding area of the arrangement.

Abstract: An assembly for arrangement to the surface of an aerodynamic profile comprises an array of actuators, which are designed as piezo actuators and plasma actuators.

Abstract: A microelectronic module for cleaning a surface is described. The microelectronic module comprises at least one voltage converter for converting a provided first voltage into a higher, lower, or identical second voltage. The module also comprises at least one actuator. The actuator comprises at least one generator for generating an ionic current, an electrical plasma, harmonic components and/or an electrostatic field from the second voltage which is provided by the voltage converter. At least the voltage converter and the actuator are disposed on a thin-film, planar substrate. At least most of at least one object adhering to the surface is removed by the actuator.

Abstract: A microelectronic module for altering the electromagnetic signature of a surface. The microelectronic module includes at least one voltage converter for converting a first voltage provided into a higher, lower or identical second voltage. Furthermore, the microelectronic module includes at least one actuator. The actuator includes at least one generator for generating an electrical plasma from the second voltage provided by the voltage converter. At least the voltage converter and the actuator are arranged on a thin-layered planar substrate. The electrical plasma generated by the actuator interacts with an electromagnetic radiation impinging on the surface, as a result of which the electromagnetic signature is altered.

Abstract: A microelectronic module for influencing a flow of a fluid is provided. The module comprises at least one voltage converter for converting a provided first voltage into a higher, lower, or identical second voltage. The module also comprises at least one active flow-influencing element for influencing the direction and/or the speed of a fluid which is flowing around and/or over the flow-influencing element. At least the voltage converter and the active flow-influencing element are disposed on a thin-film, planar substrate. The influencing of the direction and/or the speed of the fluid is dependent on a hydrodynamic acceleration as a function of the second voltage provided by the voltage converter at the flow-influencing element.

Abstract: Testing apparatus and method for testing visual systems, e.g., augmented visual systems, having a viewing unit. The testing apparatus includes a moveable holding device, which is structured to hold the viewing unit and to move the viewing unit with a rotational degree of freedom; a position detection unit structured to detect a position and an alignment of the viewing unit; and a test-conducting unit coupled to receive a detected position and an alignment of the viewing unit from the position detection unit. The test-conducting unit is configured to determine a field of view as a function of the detected position and alignment of the viewing unit, to read-in an actual field of view displayed by the viewing unit and to compare the determined field of view with the read-in actual field of view.
