摘要:
The present disclosure concerns a pressure sensor, comprising at least two adjacent electrically conductive leads disposed in a pattern on a face of a first elastomeric carrier; and an electrically resistive layer formed of a electrically resistive composite material for shunting the at least two adjacent electrically conductive leads, said electrically conducting layer disposed on a face of a second elastomeric carrier. The first and second carriers are stacked across a spacer such that the at least two adjacent electrically conductive leads faces the electrically resistive layer across a gap defined by the spacer. The gap is formed by a pocket between the carriers. The first carrier including the at least two adjacent electrically conductive leads and/or the second carrier including the electrically resistive layer are stretchable such as to upon receiving a force, exerted in a direction across the gap, reduce the gap between the electrically resistive layer and the at least two adjacent electrically conductive leads. Upon closing the gap the adjacent electrically conductive leads are shunted over a force dependent contact area and contact resistance. A gas in a gas confining structure between the carriers at least partly counteracts the exerted force.
