Abstract:
The invention relates to a tactile sensor with a sensor cell, wherein a sensor cell comprises an electrically-conducting workpiece made from flexible material and a connection to a first and a second electrode and the flexible material layers the electrical conductivity thereof under mechanical load. According to the invention, pressure distributions can be measured, by providing at least two sensor cells separated by an intervening zone, wherein two adjacent sensor cells are connected to a common first or second electrode and in the intervening zone between a first and a second adjacent sensor cell the electrically conducting workpiece of the first and the second sensor cell are at least partly separated from each other by medium with a greater specific resistance than the specific resistance of the electrically conducting workpieces.
