PROBLEM TO BE SOLVED: To provide a sensor system for measuring forces acting on a crash test dummy.SOLUTION: A system for measuring forces during a simulated dynamic vehicle event includes a plurality of sensors, a controller, and a plurality of conductors that electrically couple each sensor to the controller. Each sensor includes a layer of a pressure sensitive material arranged between an outer sheet of a carrier material and an inner sheet of the carrier material. The pressure sensitive material changes resistance in response to forces acting upon the outer sheet of the carrier material. Each of the plurality of sensors is configured to be coupled to a surface of a crash test dummy 10 or to a surface of a vehicle. The controller is configured to provide an electrical signal to each sensor, to measure the voltage across each sensor, and to determine the force acting upon each sensor based on the measured voltage. |
