Abrégé
(EN)
The invention relates to an arrangement for producing an electric field which is markedly influenced in relation to the spatial expansion thereof, and to a sensor device which comprises the same. The aim of the invention is to provide solutions which make it possible to generate a quasi-static electric alternating field which expands in a precise manner in regard to focusing in a relevant preferential area embodied as a monitoring and signal transmission area. Said aim is achieved by means of a circuit arrangement comprising a field producing electrode device which is connected as such in an LC network and which is exposed to a spatial area of the field in such a manner that the capacity of the capacitor system comprising the electrode device alters in accordance with the dielectric properties of the material present in the spatial area of the field, an insulating layer which extends on a rear side of the field electrode device which is oriented away from the spatial area of the field, a screening electrode device which extends on the rear side of the insulating layer which is oriented away from the field electrode device and a field extinction electrode device which comprises an electrode surface which is oriented towards an extinction area. The field expansion electrode device and the field extinction electrode device are arranged in such a manner and impinged upon by voltage that the spatial area of the field and the extinction area are superimposed on each other in sections. ©KIPO&WIPO 2009
