99--TECHNOLOGY TRANSFER OPPORTUNITY CARBON NANOTUBE BASED SENSORS FORSTRUCTURAL HEALTH MONITORING. LAR-16475-1 16499-1 16853-1 16900-1

NASA Langley Research Center in Hampton, VA solicits inquiries from companies interested in obtaining license rights to commercialize, manufacture and market the following technology. License rights may be issued on an exclusive or nonexclusive basis and may include specific fields of use. NASA provides no funding in conjunction with these potential licenses. THE TECHNOLOGY: Scientists at NASA Langley Research Center have developed a process for the deposition and alignment of CNTs onto metallic electrodes uses chemically functionalized lithographic patterns. This method consistently produces aligned CNTs in the defined locations. Using photo- and electron-beam lithography, NASA patterns simple Cr/Au thin film circuits on oxidized silicon substrates. The samples are then re-patterned with a CNT-attracting self-assembled monolayer of 3-aminopropyltriethoxysilane (APTES) to delineate the desired CNT locations between electrodes. During the deposition of the solution-suspended, single-wall carbon nanotubes, the application of an electric field to the metallic contacts causes alignment of the CNTs along the field direction. Global, real-time structural health monitoring systems for air and space vehicles require new strategies for the development of extremely small and lightweight sensors that are embeddable and scalable to arrays. Geometries with very thin regions (e.g., leading edges), sharp changes (e.g., wing/fuselage junctions) or areas of extremely high curvature are often impossible to instrument. NASA solves this issue with a flexible CNT-based structural health monitoring sensor for measuring the induced strain, pressure, and temperature both within and at the surface of a structurean attractive candidate for smart skin technologies. To express interest in this opportunity, please respond to [email protected] with the title of this Technology Transfer Opportunity as listed in this FBO notice and your preferred contact information. Please also provide the nature of your interest in the technology along with a brief background of your company. For more information about licensing other NASA-developed technologies, please visit the NASA Technology Transfer Portal at http://technology.nasa.gov/ . These responses are provided to members of NASA Langleys Office of Strategic Analysis and Business Development OSACB for the purpose of promoting public awareness of NASA-developed technology products, and conducting preliminary market research to determine public interest in and potential for future licensing opportunities. If direct licensing interest results from this posting, OSACB will follow the required formal licensing process of posting in the Federal Register. No follow-on procurement is expected to result from responses to this Notice.
