Item Open Access Thermal-sensing fiber devices by multimaterial codrawing(Wiley - V C H Verlag GmbH & Co. KGaA, 2006) Bayındır, Mehmet; Abouraddy, A. F.; Arnold, J.; Joannopoulos, J. D.; Fink, Y.Thermal sensing provides important information on the state of many physiological, chemical, and physical systems. However, the problem of continuously monitoring and detecting a thermal excitation over very large areas (100 m2) with high resolution (1 cm2) still remains. A solution to this problem is presented here in which a fiber (see figure) senses heat along its entire length and generates an electrical signal.Item Open Access Towards multimaterial multifunctional fibres that see, hear, sense and communicate(Nature Publishing Group, 2007) Abouraddy, A. F.; Bayındır, Mehmet; Benoit, G.; Hart, S. D.; Kuriki, K.; Orf, N.; Shapira, O.; Sorin, F.; Temelkuran, B.; Fink, Y.Virtually all electronic and optoelectronic devices necessitate a challenging assembly of conducting, semiconducting and insulating materials into specific geometries with low-scattering interfaces and microscopic feature dimensions. A variety of wafer-based processing approaches have been developed to address these requirements, which although successful are at the same time inherently restricted by the wafer size, its planar geometry and the complexity associated with sequential high-precision processing steps. In contrast, optical-fibre drawing from a macroscopic preformed rod is simpler and yields extended lengths of uniform fibres. Recently, a new family of fibres composed of conductors, semiconductors and insulators has emerged. These fibres share the basic device attributes of their traditional electronic and optoelectronic counterparts, yet are fabricated using conventional preform-based fibre-processing methods, yielding kilometres of functional fibre devices. Two complementary approaches towards realizing sophisticated functions are explored: on the single-fibre level, the integration of a multiplicity of functional components into one fibre, and on the multiple-fibre level, the assembly of large-scale two- and three-dimensional geometric constructs made of many fibres. When applied together these two approaches pave the way to multifunctional fabric systems. © 2007 Nature Publishing Group.
