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: A dispensing device and a method for dispensing liquids, in particular liquid medicaments, to persons, has a liquid-filled container an opening for dispensing the liquid at one end. A holder for holding an injection needle for injection of the liquid from the container are provided in the area of the opening. A measurement system determines a measured value, and a processing unit determines a parameter value, associated with the container, based on the measured value. At least one detection element is present at the opening and connected to a needle detection circuit. The needle detection circuit measures an electrical characteristic variable that can be picked up at the output of the detection element. The measurement result is fed to a processing unit, which calculates the parameter value and keeps it available at its output.

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.
