The program is structured as a 66-month effort spanning three phases: proving the core technical thesis, demonstrating a proof-of-concept, and achieving clinical translation and commercialization. Awards will be granted via Other Transaction (OT) instruments, with payments tied to a quarterly milestone schedule. Evaluation is based on scientific merit, feasibility, innovation, and proposer capabilities, with specific success metrics tied to Polysomnography (PSG) fidelity and diagnostic accuracy. Proposers must submit a Solution Summary by August 12, 2026, and selected candidates will proceed to a full proposal process involving a technical pitch and detailed documentation. The final proposal deadline is October 13, 2026. Requirements include active SAM.gov registration, Institutional Review Board (IRB) approval for human subjects research, and a comprehensive FDA regulatory strategy.
