Abstract:
A tactile sensor comprising: a base plate provided at a first side with a plurality of electrically conducting wires forming a row, and provided at a second side opposite to the first side of the base plate with a plurality of electrically conducting wires forming a column, each of the column wires extending through the base plate to form electrical contacts where connecting points are formed on the first side between the row wires and the electrical contacts, the first side of the base plate is provided with a covering having a pressure-dependent electrical resistance and which together with the electrical contacts of the column wires and the row wires forms one or more current paths, characterized in that the covering is divided into segments with each segment covering at least two adjacent connecting points and converting means for determining the resistances of the at least two adjacent connecting points.
