This paper describes the first phase results in personalized weapons technology utilizing biometrics, in order to develop a user only system that recognizes unique human characteristics of a specific individual. In particular, the investigation is focused on development of a Dynamic Grip Recognition (DGR) system where a sensor embedded grip and digital signal processing unit have been fabricated to perform user recognition in real time. Specifically, grips with 16 piezoelectric sensors have been developed and fitted to an M9 pistol. In addition, the required trigger switch has also been developed and incorporated into the DGR system. The DGR method performed as well in live fire (93% recognition rate) as it did in the simulator environment (95% recognition rate). Furthermore, all of the electronics, signal capture devices and sensors were demonstrated to be unaffected by the environmental extremes of live fire (over 400 shots), and to perform well.
