The Department of Defense, specifically the U.S. Army Command, Control, Computers, Communications, Cyber, Intelligence, Surveillance, and Reconnaissance (C5ISR) Center, is soliciting white papers under Broad Agency Announcement (BAA) W56KGU-23-R-RTID for the development of microsensors capable of sensing signals of interest. Proposals should focus on basic research, applied research, or advanced technology development, with an emphasis on technologies that are not tied to specific systems or hardware. This initiative is crucial for enhancing the Army's capabilities in research and technology integration, with a total funding limit of $5 million for contracts lasting up to 24 months. Interested parties must submit their white papers by February 7, 2025, and direct any technical questions by January 24, 2025, to the designated RTI BAA mailbox.
