The Department of Health and Human Services, specifically the National Institutes of Health (NIH), is seeking qualified small businesses to provide equipment and services for the development of a non-invasive magnetocardiography (MCoG) array, focusing on the Fieldline V3 Sensor. The project aims to enhance the measurement of human neurophysiology by supplying 64 sensors and related hardware, as well as research and design services, including the prototyping of a compound gradiometer. This initiative is critical for advancing the understanding of brain function through improved non-invasive observation techniques. Interested parties must submit their qualifications and capabilities by January 22, 2025, and can contact Joseph Kennedy at joseph.kennedy@nih.gov or Marlene Milgram at marlene.milgram@nih.gov for further information.
