Optical Fiber Strain Gage

Fiber and Sensor Technologies, Inc.

Blacksburg, VA

Application of NASA thermoplastic polyimides to fabrication of high-temperature optical fiber coatings and optical fiber strain gages

• Development of optical fiber strain gages for high-volume, cost-    effective manufacturing and straight-forward surface attachment   to metal and composite structural materials 
• Optical fiber strain gages offer high sensitivity and accuracy in harsh environments such as high  electromagnetic fields, high     temperatures, corrosive environments and for high strain fatigue cycling

• Current annual worldwide market for strain gage products is $144M, with a growth rate of 8.2%
• F&S proposes to capture a 5% share of the total strain gage  market as well as start new markets where there is currently no reliable competing technology

• ARPA - smart materials and structures
• USAF - smart metallic structures
• Process monitoring of advanced composites
• Health monitoring of aircraft, spacecraft and civil structures
