Abstract

A test dummy head for measuring impact surface forces and pressures applied thereto comprises a pressure-sensing face incorporated to a dummy skull structure. A plurality of thin pressure-sensitive electric films are attached to the face. The films provide electrical signals representative of a time history of pressure or force applied up to 100 individual areas of the face. A pressurized calibration chamber is employed to simplify the calibration process.
