Abstract:
The invention relates to sensor for use as a pressure and/or a force sensor. The sensor comprises an elastic and stretchable layer with material having a first Young's modulus and a first yield strain, at least a first stretchable electrode and a second stretchable electrode attached to the elastic and stretchable layer and arranged a first distance apart from each other, a flexible foil having a second Young's modulus, and electrically conductive wiring attached to the flexible foil. At least a part of the electrically conductive wiring is coupled to the stretchable electrodes in an electrically conductive manner, the first yield strain is at least 10 per cent; the first Young's modulus is less than the second Young's modulus, and the thickness of the flexible foil is at most 0.5 mm.
