Abstract: The present invention to a sensor element, particularly a sensor element useful in a vehicle occupant detection system. The sensor element comprises a first conductor and a second conductor disposed transversely with respect to one another to define a junction. In use, when a constant voltage is applied to the conductors, a first conductance is produced in the absence of applied weight to sensor element and a second conductance is produced in the presence of applied weight to the sensor element wherein the second conductance being greater than the first conductance. By incorporating a number of such junctions into matrix arrangement, the present sensor can be advantageously employed in a vehicle occupant detection system. This allows for the creation of a spreadsheet like environment where interrogation of each matrix cell provides information about the acting force.
