Abstract: The invention relates to an RFID transponder which can be operated passively. It is the object of the invention to provide RFID transponders which can be operated passively in the far field, this means over distances of at least 15-20 cm, and which can be manufactured with reduced effort and costs in miniaturized form. In the RFID transponder in accordance with the invention, at least one antenna and one integrated RFID circuit are present on a substrate, The at least one antenna is in this respect included in the form of a dipole antenna and/or patch antenna in the same silicon block, as the substrate, as the integrated circuit. The at least one antenna is in this respect arranged at a minimum distance from the integrated RFID circuit and this minimum distance depends on the respective operating frequency.

Abstract: Imprint templates for use in nanoimprint lithography methods, a nanoimprint device suitable for UV nanoimprint lithography methods and a nanostructuring method for direct structuring of a UV-sensitive imprint material on a substrate are provided. The imprint templates, nanoimprint device and nanostructuring method can be used both for ultraviolet nanoimprint lithography and for thermal nanoimprint lithography. The imprint template includes a nontransparent structured chip and a transparent substrate. An at least partially nontransparent imprint template as well as a UV source situated above the imprint template holder are used for structuring by indirect exposure by reflection of light emitted from the UV radiation source in the direction of a photoactive layer.

Abstract: An RFID-based sensing system includes a piezoelectric arrangement mountable at least partially on a structure, an RFID transponder connected to the piezoelectric arrangement, and an antenna connected to the RFID transponder and/or being integrated into the RFID transponder. The piezoelectric arrangement and/or the RFID transponder are adapted to convert kinetic energy provided by the structure into electrical energy usable for powering the RFID transponder and to generate sensing information with respect to a state of the structure. The RFID-based sensing system also includes an RFID reader.

Abstract: The invention relates to a reader antenna for use with radio frequency identification (RF ID) transponders. A reader and the transponder are connected to one another via a wireless interface. It is the object of the invention to provide a reader antenna for RFID systems whose transmission range is increased in comparison with a transmission range in a normal air environment without metallic influence with otherwise the same electrical and electromagnetic parameters. The reader antenna in accordance with the invention is provided with an antenna which is formed with a coil having at least one winding. The coil lies on a side of a carrier remote from a transponder and the carrier is made exclusively of a soft magnetic material.

Abstract: The invention relates to self-adhesive elements which can be fastened to the most varied adhesive bodies and can be used for the most varied applications. It is the object of the invention to propose elements which can be fastened in a self-adhesive manner to the different adhesive bodies, with the fastening having to be possible in a detachable manner and a multiple use of the elements being possible. At least one sensor/pickup, an electronic element, an optoelectronic element and/or an actuator are present in a self-adhesive element in accordance with the invention. Elastically deformable pimple-shaped elevated portions are formed at a surface of the element to which an adhesive body can be connected in a self-adhesive and detachable manner. The surface of the pimple-shaped elevated portions is spherically curved at least in the region which is in touching contact with the adhesive body.

Abstract: An acceleration threshold sensor includes a supporting device, a seismic mass, and a connecting device with the aid of which the seismic mass is attached to the supporting device. The connecting device is provided with a predetermined breaking point interrupting the connection between the seismic mass and the supporting device when said seismic mass is subjected to an acceleration exceeding a predetermined acceleration. This sensor has a simple structural design, can be produced at a reasonable price and is always ready to carry out a measurement. Additionally, this sensor is able to store, without any auxiliary power, that it has been subjected to an acceleration exceeding a predetermined acceleration.
