Special Notice: NATIONAL AERONAUTICS AND SPACE ADMINISTRATION is seeking inquiries from companies interested in obtaining license rights to commercialize, manufacture, and market the Split-Ring Torque Sensor (SRTS). The SRTS is a device developed by NASA in collaboration with Oceaneering and The Florida Institute for Human and Machine Cognition. It uses optical sensors to measure the position, velocity, and torque of a rotating system. The SRTS was created for use in NASA's X1 robotic exoskeleton, which is a wearable exercise machine designed to provide resistance against leg movement for astronauts in future missions. The SRTS offers greater flexibility in tailoring for specific applications and requirements and has potential uses in various fields including robotics, medical, aerospace & defense, automotive, testing & measurement, and industrial markets. Interested parties can submit a license application through NASA's Automated Technology Licensing Application System (ATLAS). No follow-on procurement is expected from this notice.
