More Information
Summary:The carpet includes two conventional fabric layers, an upper layer (1) and another, lower layer (2), the first being a visible decorative layer and the second being the base, and between the two layers (1) and (2), there is a structure forming a capacitor and formed by an insulating or dielectric layer (3) impregnated, on both surfaces, with conducting latex layers (4), this intermediate structure forming a capacitor whose capacitance variation derives from the difference in distance between the conducting layers (4) when a pressure is exerted on the actual carpet, either by a person or by an object. The carpet is supplemented with an electronic system capable of converting this distance variation into a signal, which, duly transformed, indicates the presence of an object or of a person located on the actual carpet.
