<p>An apparatus is described for detecting the location coordinates of a pressure point (8) within a sensor field, having at least one electric resistance layer (2) which is connected via electric connections (4) at the edge to a measurement and evaluation circuit (5). In order to become independent of any external supply voltage it is proposed that the electric resistance layer (2) which is provided with at least three electric connections (4) is applied to a ferroic layer (1) made of an internally charged cellular polymer.</p> |
