A sensor is configured to experience resistance changes in response to an external interaction such as force, pressure or touch. The sensor comprises a first layer of a conductive material (301, 503) attached to a first electrode (304) and a second intermediate layer of a material (302) having a resistance sensitive to said external interaction. A third layer (303) consists of a first set of fingers (504) interdigitated with a second set of fingers (505). The first set of fingers is connected to a second electrode (305) whilst the second set of fingers is attached to a third electrode (306). The first electrode is connected to one of said second electrode or said third electrode to make a parallel connection (507,508) and resistance is measured between said parallel connection and the remaining third or second electrode. A method for constructing such a sensing device for sensing an external interaction is also disclosed. |
