摘要:
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.
