Special Notice: NATIONAL AERONAUTICS AND SPACE ADMINISTRATION is seeking inquiries from companies interested in obtaining license rights to commercialize, manufacture, and market Relaxor Piezoelectric Single Crystal Multilayer Stacks for Energy Harvesting Transducers (RPSEHT). This technology, developed by NASA Langley Research Center, aims to increase the effective piezoelectric constant and mechanical energy input to energy harvesting transducers. It offers practical performance advantages, including higher mechanical-electrical coupling and conversion efficiencies, and more efficient operation across a range of vibrational frequencies. The technology is used for harvesting energy from ambient vibration sources using piezoelectric materials. Interested parties can submit a license application through NASA's Automated Technology Licensing Application System (ATLAS). For more information, visit the NASA Technology Transfer Portal. No follow-on procurement is expected from responses to this notice.
