Abstract

The tactile sensor has at least two conductive workpieces which bear on one another at a bearing area, at least one workpiece of which is produced from elastomer, with the result that it is possible to measure a contact resistance between the workpieces, which contact resistance is dependent at least on a pressure on the bearing area. At least one of the conductive workpieces comprises a conductive closed cell foam.
