tuPOY: Thermally Unstable Partially Oriented Yarns

The book paves a new dimension in electronics with the invention of a new material tuPOY which changes our perception of developing electronics. Evolving on a relatively underplayed phenomenon of static electricity in scientific exploration and application, tuPOY upholds the potential to rival both silicon and metals as electronics of the future. Devices made of tuPOY present a new emblem to the technological world, where we could envision our electronic paraphernalia from a completely different perspective. A computer the size of a big wall, which could be neatly folded and kept in our pockets when not in use and laundered on a regular basis, can be imagined possible with this invention. The concept, manufacturing process, physics and uses of tuPOY as the next generation material of electronics is described in this book.§§The production process of tuPOY encompassing transesterification and eta polymerization is developed and articulately arrested using an innovatively formulated retardant. The retardant forms an energy barrier, alternating between the polymer chains in tuPOY preventing the polycondensation process of stabilization to complete. The retardant embedded in the reaction is characterized such that it does not react with tuPOY or alter its chemical and structural properties.§Conceptual advancement in material and electrical sciences precipitates from manipulating the sensing, radiating and processing properties of tuPOY. Correlational investigation of the electric charge flow on tuPOY lattice through transmission and scanning electron microscopy, validates the conducting properties. Responsive stimuli and ejection quantization of hydrogen nuclei under the nuclear magnetic resonance helps characterize the thermally unstable properties of tuPOY. Emission and absorption of infrared radiation on tuPOY lattice categorizes the electromagnetic spectrum, in which tuPOY exhibits radiation characteristics. Fingerprinting through infrared spectral domain by Fourier transform and micrographical analysis of X-ray di raction on lattice validates similar morphology of tuPOY and partially oriented yarns conforming its inheritance to the family of textiles. Endurance of a higher di raction count of the X-rays on tuPOY lattice, in comparison to a regular yarn, attributes to the permanent thermal unstability and presence of an inherent charge threshold, countenancing logical operations and use as processing elements. Theoretical modeling of tuPOY is characterized by steady-state equations exploiting interchanges based on the lattice kinetics, which mathematizes an Interchange Phenomenon in tuPOY. The numerical manifestations calibrate mathematically, tuPOY's response to any external physical impetus like charge, heat or energy flow. For physical testament of the sensing properties and validation of the theoretical model, tuPOY is manifested as a sensor exploitable in a plethora of applications. A microstrip patch antenna designed by amalgamation of tuPOY, raw silk and polynylon composites experimentally verifies the radiation properties. The conduction properties are satiated by successful use of tuPOY as charge conducting wires. A Power Generating Unit (PGU) with tuPOY as its primary element scavenges power from thermal energy presenting a new dimension in operational power dynamics. The unified synergetic operations of tuPOY devices are protruded through pervasive computing environment in a case study embodying a wireless body area network. Circadian variation in physiological signals reflecting progression of disease in more than 2000 subjects are evaluated on the test bed, yielding impressive results. This book should be of interest to new materials researchers, developers, and manufacturers across the globe.§§
