The Department of Defense, specifically the Navy, is seeking innovative solutions through the Small Business Innovation Research (SBIR) program for the development of a Compact Underwater Electromagnetic (UEM) Sensor with Internal Data Logging. The objective is to create a compact, portable sensor capable of measuring magnetic and electric fields in underwater environments, with a design that allows for easy deployment and recovery, and the ability to operate for up to seven days. This technology is crucial for both military applications, such as collecting UEM signature measurements of naval vessels, and civilian uses, including geological surveys and ocean research. The solicitation is currently in pre-release, with an open date of January 8, 2025, and a close date of February 5, 2025. Interested parties can find more information and submit proposals through the official SBIR website.
