TECHNICAL ABSTRACT (Limit 2000 characters, approximately 200 words)
Future long-duration, crewed space habitat systems will be inflatable structures. This type of structure is advantageous in that it is not limited to the diameter of the launch vehicle and can therefore provide a greater volume of living and work space. Unlike conventional metal structures, however, softbody inflatables require support members to maintain their desired shapes. Despite their robustness, the webbings strain due to the internal habitat inflation pressure and resulting stress. To measure the relatively large strains that occur in the webbings during the inflation of model habitats used during the design process, pin or clip-on extensometers are used, but the pins damage the material and are unacceptable. Strain sensors directly integrated into or onto low-strain webbing fabrics like Dyneema, Vectran would allow the determination of webbing loads during the inflation process as well as during the use lifetime of the habitat. Such webbing-integrated elongation sensors would have two primary uses. First, they would be used to determine and map mechanical loads during the inflation process to insure that the habitat attains proper design form. Second, in the long-term, they would be used to monitor the gradual creep of the webbings that must be balanced by inflation forces to maintain proper figure.
The purpose of the proposed program is to address this specific NASA need - to develop fabric extensometers that can be built into habitat webbings during their manufacture and used to measure loads during inflation and long-term use. To that end, NanoSonic will build on its Metal Rubber� (MR�) technology to create fabric sensor materials that are electrically conductive and mechanically flexible, tailored to the required performance metrics of the structural webbing materials.

POTENTIAL NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
In addition to expandable space habitats, such elastomeric large strain sensors have other direct aerospace applications, such as the measurement of strain on high altitude airships and balloons, spacecraft fuel bladders, and space-based deployable flexible radars, photovoltaic arrays and antennas.

POTENTIAL NON-NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
The materials developed under this NASA STTR program have extensive non-NASA commercial applications including flexible radome structures, dwellings for polar or desert-based scientists, and even hyperbaric chambers for health clubs or hospitals.
