Sensor Systems for Measuring Helmet-Head-Brain Response to Blast

Abstract : From World War I (WWI) to the war in Iraq, helmets have transitioned from steel to Kevlar composite materials. Just prior to WWI, helmets were non-existent because mobility and weight requirements took precedence over protection. Today mobility, weight, comfort, and protection factor into helmet design based on current threats from various ammunition, fragmentation threats, and operational environments. Inside the helmet, liners have evolved from leather to plastic suspension to sophisticated energy-absorbing padded liners, and new prototype suspensions are being tested every year to improve comfort and increase protection. Because of recent medical advances, it is apparent that experimental methods, measurement devices, and newer classes of helmets are necessary to provide warfighters with the best personal protection equipment for combating traumatic brain injuries (TBI).
