Abstract:
A plate-shaped chip supporting body has a number of write/read contacts for exchanging data with an external chip card. A number of corresponding terminal panels which are electrically connected to the write/read contacts of the front flat side, are arranged on the opposite rear side of the chip supporting body. A sensor ship is attached to the rear side of the chip supporting body and has contact pads electrically connected to the terminal panels of the chip supporting body. Contact panels on the flat side of the sensor chip are oriented toward the chip supporting body and are connected to the pad contact, which are located on the opposite flat side of the sensor chip, by at least one electrical signal line path passing through the sensor chip, and the contact panels are connected to the terminal panels of the chip supporting body by electrically conductive material.
Abstract:
A nanostructure is provided on a substrate by forming at least one multi-electrode arrangement on the substrate, wherein said electrodes comprise respective electrode areas projected with respect to the opposite electrode ends which extend along a line in such a way that the adjacent ends produce a respectively frequency time-variable potential difference. A suspension of nano-object such as nanotubes, nanowires and/or carbon nanotubes is produced and then transferred to the substrate between the adjacent ends. The assembly of respective individual nano-objects is dielectrophoreticly deposited on the line between said adjacent ends, and the assembly of respective nano-objects is fused in the area of the ends in such a way that the nanostructure is formed.
Abstract:
A connection device for random connection of a first member of first transmission/reception units with a second number of second transmission/reception units has a switching matrix that includes a third number of controllable micromechanical switching elements that are respectively activatable to establish a connection between one of the first transmission/reception units and one of the second transmission/reception units. A control circuit selectively activates the respective micromechanical switching elements to selectively establish respective connections between the first number of first transmission/reception units and the second number of transmission/reception units.
Abstract:
A separable connection is created between at least one transfer support and the conductor structure. The transfer support including the conductor structure and the substrate are joined together such that a connection that is stronger than the separable connection between the transfer support and the conductor structure is created between the conductor structure and the substrate. The separable connection between the transfer support and the conductor structure of the transfer support is separated while the connection between the conductor structure and the substrate remains intact. The method is particularly suitable for laterally disposing conductor structures comprising nanotubes at relatively low temperatures (T
Abstract:
The embodiments relate to a device, especially a microsystem, which comprises an energy converter unit having an electrode structure for the capacitive conversion of mechanical energy to electrical energy The electrode structure includes a first electrode and a second electrode the distance of which to the first electrode is variable. The device according to the invention also comprises a load circuit via which the first and second electrode are interconnected in an electroconductive manner. A transmitter is coupled to the second electrodes. The distance between the first and the second electrode can be varied by displacing the transmitter and the displacement of the transmitter can be effected in a countactles manner by interaction of the transmitter with a mobile part.

Abstract:
A device to extract material of a material reservoir has at least one guide tube with internal space and with an inner wall surrounding the internal space; at least one sled that can implement a sled translation movement in the inner space along a longitudinal alignment of the guide tube; and at least one collection unit with collection surface to collect the material. The collection unit and the sled are coupled to one another such that the sled translation movement of the sled leads to a collection translation movement of the collection surface of the collection unit, and such that the collection surface can be inserted into the material reservoir and be withdrawn from the material reservoir. A rotation mechanism that is operated manually or automatically can be provided with which a wire, which acts as a collection device, can be displaced in vivo over a length of 1 mm to up to 2 cm within a venous cannula. The invention is used in medical technology, for example, to collect cells from a reservoir in the form of a bodily fluid.
Abstract:
