Description: introduction, and commercialization transition of a unique fully integrated, miniature size, light weight, ultra-low power, and wireless communication weaved distributed optical fiber sensor (DIFOSTM) SHM system suitable for the global monitoring of passive and dynamic – axial and bi-axial – stresses and shape history within the canopy broadcloth fabric of large and entire cross-sections of NASA’s disk-gap-band (DGB) parachutes planned for the Mars mission landings. A specific commercial spin-off application of the DIFOSTM technology is for the use of the DIFOSTM sensor network interrogation systems as well as high performance “Smart” expandable fabrics for applications in avionics and aerospace environments, as well as in personal physiological vital signs monitoring sensors for aerospace and consumer markets. The DIFOSTM technology addresses a global commercial avionics and aerospace market for the instrumentation of over 6000 airplanes with DIFOS systems and peripheral components with a potential business opportunity value exceeding over $ 6-billion in DIFOSTM systems.

Benefits: All of NASA's current and future space vehicle programs will benefit significantly from this project. Specific NASA applications of the propose DIFOS SHM system include un- attended inspections on large and complex composite structures, i.e., decelerator systems, parachutes and ballutes, honeycomb structures, multi-wall pressure vessels, thermal blankets, meteoroid shields, batteries, etc., commonly found in spacecraft, and habitats, and support infrastructures. In addition vital sign physiology monitors for the spacesuit crew.

The DIFOS SHM technology addresses the global SHM/NDE aerospace and avionics market expected to grow over 6.8-billion in 2020, and the Smart-Fabrics Market expected to grow to over 4.7-billion in 2020, with the potential to instrument over 6000 space flight vehicles, military, and commercial airplanes, drones, as well as performance Smart clothing with DIFOSTM SHM systems.
