Paper P3-01“Harvesting Mechanical and Thermal Energy by Combining ZnO Nanowires and NiTi Shape Memory Alloy” Opportunity : Lawrence Livermore National Laboratory (LLNL), operated by the Lawrence Livermore National Security (LLNS), LLC under contract no. DE-AC52-07NA27344 (Contract 44) with the U.S. Department of Energy (DOE), is offering the opportunity to establish a collaboration to conduct further research and development of this technology and obtain licensing rights for commercialization. Background : Waste heat is generated whenever work is performed. Harvesting such waste heat can increase the efficiency of engines, be used to power numerous devices eliminating the need for auxiliary power sources, and significantly reduce power requirements. Various methods have been used to harvest waste heat, the most important of which is through thermoelectric materials. Description : LLNL's invention can harvest mechanical and thermal energy by combining nanowires and phase change materials. The apparatus, systems, and methods provide thermoelectric elements having a very large number of alternating layers of semiconductor material all having the same crystalline structure. This makes the vapor deposition process easy because the exact ratio of the materials in the layers is not critical. In a preferred embodiment, the layers are grown under conditions which cause them to be strained at their operating temperature range in order to improve the thermoelectric properties. See attached presentation Paper P3-01"Harvesting Mechanical and Thermal Energy by Combining ZnO Nanowires and NiTi Shape Memory Alloy" Spring MRS Meeting, April 22, 2014 Advantages : LLNL inventors have demonstrated that materials produced using this invention provide figure of merit more than six times that of other thermoelectric materials. Moreover, the current produced by this method can be continuous, compared to other purely mechanical thermoelectrics, which demonstrate a large hysteresis with temperature Potential Applications LLNL's apparatus, systems, and methods provides power generation harvested from low quality waste heat and external motion. This invention can also be used to power small sensors and actuator devices requiring microwatts of power or infrequent power from energy stored in a supercapacitor. Development Status: LLNL is seeking industry partners with a demonstrated ability to bring such inventions to the market. Moving critical technology beyond the Laboratory to the commercial world helps our licensees gain a competitive edge in the marketplace. All licensing activities are conducted under policies relating to the strict nondisclosure of company proprietary information. Please visit the IPO website at https://ipo.llnl.gov/resources/industry/working-with-us for more information on working with LLNL and the industrial partnering and technology transfer process. Note: THIS IS NOT A PROCUREMENT. Companies interested in commercializing LLNL's Harvesting Mechanical and Thermal Energy Combining Nanowires and Phase Change Materials invention should provide a written statement of interest, which includes the following: 1. Company Name and address. 2. The name, address, and telephone number of a point of contact. •3. A description of corporate expertise and facilities relevant to commercializing this technology. Written responses should be directed to: Lawrence Livermore National Laboratory Industrial Partnerships Office P.O. Box 808, L-795 Livermore, CA 94551-0808 Attention: FBO 293-15 Please provide your written statement within thirty (30) days from the date this announcement is published to ensure consideration of your interest in LLNL's Harvesting Mechanical and Thermal Energy Combining Nanowires and Phase Change Materials invention.
