Navy SBIR Research and Development for High-Sensitivity TMR Magnetometers

The Department of the Navy is seeking SBIR research and development proposals for compact, high-sensitivity tunneling magnetoresistive (TMR) magnetometers. - Government buyer: Department of the Navy, through the Office of Naval Research (ONR); Navy acquisition program office involvement is anticipated for later-phase metrics and transition. - OEMs and vendors: No OEMs, vendors, or commercial manufacturers are named. - Requested technology: Compact, low-power, low-cost TMR magnetometers for one-way attack vehicles, expeditionary and mine warfare, swarming systems, and unmanned underwater vehicles (UUVs). - Target per-axis specifications: under 10 × 10 mm size, under 100 mW power, sensitivity under 50 pT/√Hz at 1 Hz, DC–500 kHz frequency range, and a −100 to 100 µT dynamic range. - Planned work: Phase I develops a single-axis sensor concept and calibration approach; Phase II fabricates and evaluates 6 or 9 vector-configuration prototype systems, calibrates each sensor, and supports Navy testing; Phase III advances the prototype toward Navy validation and UUV program transition, with potential commercial applications in magnetic surveying and unexploded ordnance detection. - Notable requirements: Each sensor is to receive voltage-to-field calibration. The topic also identifies ITAR/EAR restrictions and a CMMC Level 2 (Self) requirement.
