Description

The Department of Defense (DoD) is seeking proposals for a novel fieldable device for the detection of sleep microarousals. The device should be wearable and able to measure microarousals during sleep, which are brief moments of waking activity with a rapid return to sleep. Current sleep measurement devices on the market struggle to capture these microarousals, which are associated with negative health outcomes and altered daytime functioning. The device should be comfortable, unobtrusive, and wireless, with the ability to toggle between saving data on the device or wirelessly transmitting it using military telecommunication standards.

In Phase I, the objective is to develop a wearable device that can measure sleep microarousals. The device should be able to detect microarousals in real-time and have a small rechargeable battery lasting at least 12 hours. Phase II will involve testing the device on human subjects to determine if microarousals measured during sleep are related to next day cognitive performance. The device should be able to detect microarousals with 85% accuracy compared to polysomnography and predict next day cognitive performance with 85% accuracy, surpassing the predictive ability of total sleep time alone.

If successful, the fieldable device could have applications in both the commercial market and within the DoD. In the commercial market, the device could be used to improve performance modeling and scheduling for high-risk jobs such as pilots, truck drivers, and law enforcement. It could also be embraced by the growing sleep device consumer market as a more accurate way to measure sleep and test the efficacy of sleep interventions. Within the DoD, the device's information could potentially be integrated into existing tools and algorithms for performance prediction.

DOD SBIR 24.4 Annual - Forward Looking Infrared (FLIR) Dual Band Focal Plane Array in High Definition Format
Active
Department of Defense
The Department of Defense (DOD) is seeking proposals for the development of a small energy-efficient self-contained transceiver capable of wireless communication without using traditional radio frequency (RF) transport. The goal is to utilize a non-standard means of signal communication, such as magnetic, acoustic, or infrared, that is difficult to detect and report in covert activities. The transceiver should be highly resistant to interference, detection, and exploitation, and be self-contained, man-portable, easily concealable, and field programmable. The project duration is divided into two phases: Phase I involves creating a plausible design and rationale supporting the solution, while Phase II focuses on developing and testing a prototype that demonstrates the desired capabilities. The project aligns with the Army's smart sensing initiatives and aims to provide an innovative alternate means of low probability of detection (LPD) and low probability of interception (LPI) communications. The solicitation is open until March 31, 2025. For more information, visit the [solicitation link](https://www.sbir.gov/node/2496863).

Department of Defense
The Department of Defense (DOD) is seeking proposals for the development of precision contact lens eye tracking sensors for Extended Reality (XR) interaction, training optimization, and cognitive monitoring. The objective is to enhance command and control capabilities in XR environments, optimize training, and enable real-time adaptive systems. Current eye tracking technologies lack the necessary precision and ruggedness for military operations. The use of contact lens-based eye tracking would allow for operational integration into various dynamic scenarios, including manned and unmanned air operations and ground vehicle systems. The proposed project includes feasibility studies, the development of a working prototype, and human factors feasibility studies. The technology has potential applications in academic research, health monitoring, and various market applications. The project is open for proposals until March 31, 2025.

DOD SBIR 24.4 Annual - Low Cost Persistent Multi Sensor Surveillance

Department of Defense
The Department of Defense (DOD) is seeking proposals for the topic of "Low Cost Persistent Multi Sensor Surveillance" as part of their SBIR program. The objective of this topic is to develop environmentally hardened sensor nodes that can persistently monitor Radio Frequency (RF), weather conditions, and/or personnel access of remote islands leased on the Kwajalein Atoll for the U.S. Army's Reagan Test Site (RTS). The solutions should be independent of external power sources or communications networks, as there are no cellular or Wi-Fi communications, nor power source, in these areas. The solutions must also be capable of operating in harsh environmental conditions, including heat, humidity, regular rainfall, salt spray, and high atmospheric salinity. The data collected by these sensor nodes will be used for situational awareness, safety, security, and mission planning and support. The solicitation is open for both full or partial solutions, and Phase I proposals with a cost of up to $250,000 for a 6-month period of performance are being accepted. Phase I will involve researching and developing the system/network architecture, designing the hardware components, and proposing power source designs and networking techniques. By the end of Phase I, the awardee should have detailed descriptions of the proposed technologies. In Phase II, the awardee will produce a single prototype that demonstrates the capabilities and methodologies at a minimum of TRL4. They will also develop a user interface and display for situational awareness of sensor control and monitoring. The potential applications of this technology include wireless remote sensing for public safety, health, fitness, and wildlife dual-usages. Some examples of dual uses of remote sensing include anti-poaching efforts, remote environmental sensors enabled by low-Earth orbit satellites, wildfire early recognition sensor systems, agriculture and crop performance monitoring, and urban pollution source detection.

The Department of Defense (DOD) is seeking proposals for the development of a portable Diamond Nitrogen-Vacancy (NV) Center-based Quantum Magnetometer for enhanced detection of Person-Borne Improvised Explosive Devices (PBIEDs). Quantum magnetometers utilizing Diamond NV technology offer significant advancements in sensitivity and precision for detecting minor fluctuations in magnetic fields. The magnetometers provide benefits such as exceptional sensitivity, robustness, durability, and non-invasive detection. However, challenges include manufacturing complexity, cost, false positives in metal-rich environments, and limitations in detection range and depth. The solicitation invites proposals for designing a portable Diamond NV-based Quantum Magnetometer that addresses these challenges and demonstrates a thorough understanding of operational contexts. The project will be conducted in three phases: Phase I involves foundational groundwork and design schematics, Phase II focuses on developing a working prototype, and Phase III involves refining the final deployable equipment and procedures. The development of a better magnetometer has the potential to provide significant benefits to numerous programs within the DoD. The deadline for proposal submission is March 31, 2025.
