Until 1987, force measuring sensor (load cell) development was primarily for the Hybrid III 50th percentile, adult, male dummy.  The development of more complex occupant protection systems, in the automotive industry, has resulted in the need for additional anthropomorphic test dummies. They include infants, small children, adult male and female dummies as well as dummies designed specifically for side impact crash testing. The new dummies have increased measurement capabilities to better evaluate the interaction of the occupant with the restraint system and the vehicle interior. Load cells have been developed to meet the needs of the new dummies as well as to increase the measurement capability of the Hybrid III 50th dummy.
