TECHNICAL ABSTRACT (Limit 2000 characters, approximately 200 words)
The objective of this NASA SBIR program is to develop conformal Metal RubberTM sensor skins for the distributed measurement of wall shear or skin friction on rotorcraft rotor blades. The sensor skin arrays would allow the direct two-dimensional mapping of both orthogonal components of tangential skin friction on rotor blade surfaces without requiring large recessed cavities within the blade structure. Metal RubberTM skin friction sensor element prototypes have been demonstrated on small laboratory flow test articles. Wall shear measurement data are important to 1) establishing boundary conditions for computational fluid dynamics (CFD) analysis of air vehicle boundary layer flow and turbulence, and 2) active flight control of air platforms. During Phase I, NanoSonic would design, fabricate and test new, large-area Metal RubberTM sensor skin materials and arrays capable of surviving the thermal, mechanical, UV and chemical environment of operational aircraft, and work with NASA and industrial partners to transition the use of such sensor skins to use on rotor blade wind tunnel models. The new high performance Metal RubberTM materials, sensor skin arrays, and data acquisition and signal processing electronics would be evaluated using multiple air and water flow systems at NanoSonic and in wind tunnel facilities at a partner institution.

POTENTIAL NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
NASA applications of conformal Metal RubberTM 'sensor skin' arrays include 1) direct distributed measurement of air data on wind tunnel models to establish CFD boundary conditions as part of air vehicle development, 2) co-located measurement and mapping of skin friction and pressure on full-scale flight test aircraft, 3) conformal, skin-like 2D tactile sensor arrays for astronaut-assisted or telerobotic manipulators, and 4) distributed physiological sensor arrays of blood pressure, and heart and respiration rate for astronauts during extended space missions and extravehicular activities.

POTENTIAL NON-NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
Non-NASA applications of similar conformal Metal RubberTM 'sensor skin' arrays include 1) measurement of skin friction and pressure on operational hydrocraft, 2) tactile sensor skin arrays that can flex in addition to bend, 3) 2D strain and pressure sensor arrays for biomedical instrumentation, and 3) sensors for high performance military aircraft, especially UAVs and Morphing Aircraft that require active air data sensing and flow control to optimize performance.

NASA's technology taxonomy has been developed by the SBIR-STTR program to disseminate awareness of proposed and awarded R/R&D in the agency. It is a listing of over 100 technologies, sorted into broad categories, of interest to NASA.
