The Department of Defense (DoD) is seeking proposals for the development of technology to drive 60-day runtimes in wearable devices. The Defense Health Agency is specifically interested in hardware and embedded software technologies integrated onto a self-powered on-body sensor. The wearable device should include physiological and environmental sensing, recording, and processing capabilities, and operate off a non-AC/DC power supply. The device should be capable of a minimum of 60-day runtime and be able to operate in disconnected military relevant environments. The developed wearable devices will also require additional DoD relevant security measures. This funding opportunity aims to address the power supply limitations of commercially available wearable devices and enable continuous remote physiological monitoring to inform readiness metrics under austere military conditions. Phase I proposals should present a plan for the design, development, and fabrication of an on-body wearable, physiological sensor that operates on a non-AC/DC power source and demonstrates a 60-day or greater runtime. Phase II will focus on prototype development and refinement of the proof-of-concept device, with a demonstration of a 60-day runtime and interoperability with existing DoD wireless infrastructure. Phase III will involve longitudinal evaluation of the prototype in an operational environment and lay out plans for mass production, support, and service of the developed wearable devices. The deadline for proposal submission is October 18, 2023. For more information, visit the solicitation link.
