Thesis (Ph.D.)--North Carolina State University, 2007.

Electronic and optoelectronic textiles are an emerging area with many potential applications including the distribution of sensors within fabrics. One of the principle challenges of textile based electronics is to understand how the conductors and fiber optics behave under the mechanical forces of construction and use. Thus, first part of this thesis focuses on the development of fiber optic sensors that are sensitive, yet robust enough to be incorporated into textiles. The second part of the thesis focuses on the problem of understanding the bending stiffness of fabric-based electrical circuits.

520 $a Electronic and optoelectronic textiles are an emerging area with many potential applications including the distribution of sensors within fabrics. One of the principle challenges of textile based electronics is to understand how the conductors and fiber optics behave under the mechanical forces of construction and use. Thus, first part of this thesis focuses on the development of fiber optic sensors that are sensitive, yet robust enough to be incorporated into textiles. The second part of the thesis focuses on the problem of understanding the bending stiffness of fabric-based electrical circuits.
520 $a Several novel fiber optic sensors are developed in this thesis, with the main focus on optical affinity sensors that employ surface plasmon resonance effects that are sensitive to local changes in the surrounding refractive index. These sensors can be employed to monitor the change of concentration of a chemical or adsorption of chemical or biological molecules on the surface of the sensor. A variety of techniques to control the surface plasmon are investigated, including annealing of gold thin films to form discontinuous and islanded thin films with nanoscale size dimensions, colloidal nanoparticles of gold, and surface plasmon engineered thin films where the extraordinary transmission of arrays of sub wavelength apertures can be exploited. In general these sensors are tested by changing the surrounding refractive index medium and monitoring the optical transmission. To demonstrate the detection of molecules, the detection of Streptavidin binding to Biotin is demonstrated. A variety of novel in-line temperature sensors are also developed, by incorporating temperature sensitive nanoparticles within the core of the optical fiber, or by constructing an inline Fabry-Perot cavity within the structure of the fiber.
520 $a In the second part of the thesis, the problem of bending stiffness of fabric-based electrical circuits is addressed. A theoretical model that explains the effect of incorporating finite number of rigid threads in a fabric, in the warp and weft directions, along with flexible threads on the bending rigidity of the fabric is presented. The theoretical models are then compared with experimental measurements. An elastica-based theoretical model is developed and applied to fabrics containing multiple welded, fused, or soldered interconnects at the crossover point.
