Abstract: An arrangement for determining the moisture of an object, in particular the moisture of human skin, has an electrically insulating carrier layer onto which the following units are applied: at least two electrodes, in particular interdigital electrodes, which are arranged on a first face of the carrier layer; a digital capacitance measuring device, to which the electrodes are connected; an NFC transponder which comprises an antenna and to which the measurement results of the capacitance measuring device are supplied in order to be forwarded wirelessly via the antenna, wherein the NFC transponder and the capacitance measuring device are arranged in the same chip in particular; and a shielding, which lies on the carrier layer face opposite the first face and which is connected to system ground of the capacitance measuring device in particular.

Abstract: The present disclosure relates to a sensor for a capacitive determination of a filling level of a cartridge filled with a liquid substance. The sensor comprises a planar flexible foil arrangeable to an outer circumference of a tubular shaped barrel of the cartridge. The foil has at least a sensing zone, a communication zone and at least a first electrode. The foil further comprises least a second electrode located in the sensing zone, a processor electrically connected with the at least first and second electrodes, and an antenna located in the communication zone. The antenna is electrically connected with the processor.

Abstract: An NFC transponder assembly includes an NFC communication unit and an antenna coil connected to the communication unit. The assembly draws energy from an electromagnetic field at the antenna coil via the antenna coil and establishes an NFC communication link with a data communication device via the antenna coil. A first switch is activated to activate the antenna coil. A second electric switch, parallel to the first switch, is open in the inactive state. The assembly closes the second switch after the first switch is actuated and keeps the second switch closed for a period of time after terminating the actuation of the first switch such that the antenna coil is activated for that period of time and ready to transmit data. The assembly opens the second switch after the period of time has expired such that the antenna coil is deactivated and no longer ready to transmit data.

Abstract: A device for determining the condition of a person's skin includes a flat plaster sheet bindable to the skin and made of a flexible, non-conductive film with a recess for application of cosmetic or medical preparations to the skin from outside. Contact electrodes disposed on the skin as a sensor for the flat skin plaster sheet are connected by NFC technology with a voltage supply unit having an impedance and resistance and/or capacitance measuring unit. A passive communication unit with an antenna loop is supplied with measurement or skin resistance and/or capacitance data and is accessible by an NFC-enabled external communication device. The recess has a rectangular, square, circular, hexagonal or octagonal shape, pairs of diametrically opposed, associated electrodes in the flat plaster film sheet and opposite edges being rectilinear, parallel, disposed in vicinity of opposing edges of the recess and connected with the measurement unit.

Abstract: A measuring device for detecting and evaluating an impact, jolt or the like is formed with an impact face, against which the impact, jolt or pulse which is to be evaluated strikes. A sensor, for example a force sensor, detects values of the force which act on the impact face as a result. A sensor, for example an acceleration sensor, detects values of the acceleration which act on the impact face as a result. An evaluation unit processes the determined force and acceleration values.
