The Department of Defense (DOD) is seeking proposals for a Small Business Innovation Research (SBIR) program focused on the topic of "Technology to Drive Extreme Runtime in Wearable Devices". The objective of this program is to develop a software technology that can be coupled with existing wearable devices to enable continuous remote monitoring in austere military environments. The software application should provide onboard computing and processing of sleep and fatigue data, significantly reducing power consumption and data size. The technology should be able to capture heart-rate, heart-rate variability, activity/motion, timing of sleep periods, and asleep/awake status for a duration of at least 30 days (threshold) or 60 days (objective) without charge. The development of this technology will greatly improve the ability to field wearable devices for long periods of time in disrupted, disconnected, intermittent, and low-bandwidth environments. The program consists of three phases: Phase I involves developing a proof of concept for the software application, Phase II focuses on testing and fielding the application with at least 50 devices, and Phase III involves integrating the prototypes into deployed Naval vessels and transitioning the finalized product to the Naval Surface Force. The technology has potential applications in the commercial sector, including sporting teams, extreme athletes, and emergency services. The deadline for proposal submission is February 21, 2024.
