Abstract

A force sensor system (100) is presented herein that comprises a carrier substrate (1), a sensor layer thereon and a signal processor (5). The sensor layer has a contact sensitive surface (11) and comprises a plurality of resiliently deformable sensor cells (3a, 3b,...). The sensor cells each form an enclosure around a pocket (2a, 2b, 2c, 2d) communicating with a pressure sensor (4a, 4b, 4c, 4d) that is configured to provide a respective pressure signal (Spa, Spb,...) indicative for an inside pressure inside the pocket. The inside pressure of a sensor cell is dependent on an external force exerted thereon through the contact sensitive surface according to a pressure-force relationship, wherein the pressure to force relationship is dependent on a lateral direction of the external force for two or more of the plurality of sensor cells in a mutually different manner. The signal processor (5) is configured to receive the pressure signals and to provide an output sensor signal based on the received pressure signals.
