Prevent Biometrics has been used since 2017 in military applications to monitor blunt forces and blast overpressure. This work has been assisted by the United States Defense Department (DoD), who has awarded Prevent Biometrics and its collaborators over $8 million of competitive, peer-reviewed funding during that time.

The patented Prevent Biometrics “Intelligent Mouthguard” (IMG) system measures and automatically reports real-time blunt force head acceleration events (HAE). Military training environments have proven to be an especially good setting for the IMG, with 100,000+ HAE’s collected in over 3,000 service members. A key priority for the DoD has been to quantify HAE’s in parachute landing falls (PLF), hand-to-hand combative training and military service academy training.

The core Prevent Biometrics technology has found a dual purpose as part of a combination sensor – aka “Combo Sensor” – that is also being used to count and estimate blast wave and acoustic exposures in training. The patent-pending Combo Sensor has been used under the helmet, on the helmet, as well as on the uniform. A multitude of training environments have been monitored: M107 0.50cal suppressed and unsuppressed rifle, M2A1 0.50cal machine gun, MK19 grenade launcher, M4 Carl Gustaf recoilless rifle, M72 Light Anti-Armor Weapon (LAW), M141 Bunker Defeat Munition (BDM), 81mm/120mm mortars, close quarter combat (CQC) environments and variety of explosive breaching applications. The benefit of the Prevent Biometrics Combo Sensor is that a single hardware and software platform can be used to monitor blast and blunt forces in real time in the military training environment.
