TECHNICAL ABSTRACT (Limit 2000 characters, approximately 200 words)
The NASA Phase I program would develop and demonstrate semiconductor nanomembrane (NM) based flight sensors and arrays on flexible substrates, using SOI (Silicon on Insulator) silicon NM technique in combination with our pioneering HybridsilTM copolymer nanocomposite materials. Specifically, ultrathin nanostructured sensor skins with integrated interconnect elements and electronic devices that can be applied to new or existing wind tunnel models for skin friction analysis would be developed. NanoSonic has demonstrated the feasibility of NM transducer materials in such sensor skins for the measurement of flow-induced skin friction and pressure. Early experimental results have compared very favorably with data from other sensor gages.Major improvements from the previous Metal RubberTM based sensor include faster response time and less temperature dependence due to the high carrier mobility with the inorganic NMs. During this NASA STTR program, a semiconductor NM based distributed sensor array will be developed (Phase I) and deployed to measure in-flight (Phase II) the surface properties on an airplane wing surface. The properties that will be measured will include shear stress and pressure. With the high frequency response of the NM sensors (100 kHz), it is possible that laminar to turbulence transition can be detected. In phase I, an existing Mach 0.7 wind tunnel will be used to check out the performance of the sensors.

POTENTIAL NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
The anticipated initial market of the NM sensor skin arrays is for flight testing and wind tunnel testing of flow models for NASA flight research centers. An appreciation of the instrumentation issues obtained by working with such centers would allow improvements in sensor materials, electronics and packaging, and potentially allow the transition of related products to operational vehicles. The commercialization potential of the NM technology developed through this NASA STTR program lies in four areas, namely 1) NM sensor skin arrays for the measurement of skin friction, 2) Broader sensor skin arrays for the measurement of pressure, 3) Single-element air or water flow sensors, and 4) NM material itself.

POTENTIAL NON-NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
Primary customers would be university, government laboratory and aerospace industry researchers. Small, unmanned air vehicles large enough to carry the extra load associated with electronics and power, and operationally sophisticated enough to require air data sensors would be a likely first military platform use. Distributed pressure mapping on air vehicles as well as in biomedical devices and other systems may have merit. Further, the thin film shear sensor elements may be used as air flow or water flow devices in systems where either the low weight, low surface profile, lack of need for space below the flow surface, or high sensitivity at a low cost are needed.
