Notice description

Source text reproduced without an AI summary.

The Advanced Research Projects Agency for Health (ARPA-H) seeks proposals for the Restorative & health-Enhancing Sleep Time (REST) program, a bold effort to transform how poor sleep is measured and treated by enabling objective, home-based, closed-loop technologies that detect health-relevant sleep microstructures and respond to them in real time. If successful, REST will establish the technical foundation for a new generation of sleep health technologies that are objective, personalized, and capable of improving long-term health outcomes at scale. 6/16: Amendment 1 updates links within the ISO 6/18: Amendment 2 adds Section 6.5 Questions and Answers 6/24: Amendment 3 makes various edits for clarification in Sections 1-3.
