Wearable sensor technology will shape the future of biosurveillance for the DoD, equipping the Warfighter with personal chemical, biological, and radiological exposure detection devices that can monitor both the environment around them, as well as the health of each individual service member. As wearable chemical and biological sensors become increasingly integrated into real-time interfaces, it becomes imperative for the Department of Defense (DoD) to identify and assess those sensor technologies that can be quickly developed and integrated into useable and deployable systems. The Edgewood Chemical Biological Center (ECBC) has conducted a technology survey of the wearable sensor technology market for the Defense Threat Reduction Agency/Joint Science and Technology Office (DTRA/JSTO).
