Abstract: A sensor for measuring the degradation of a fabric property is disclosed. The sensor includes a conductive track and a sacrificial material coupled to the conductive track, such that degradation of the sacrificial material results in reduction or loss of electrical conductivity of the conductive track. A method of measuring the performance degradation of a fabric, using a sensor is also provided. The method includes the step of measuring the electrical resistance of the sensor, and comparing the result to a known or empirically measured value to estimate the remaining useful life of the fabric performance.

Abstract: Embodiments of the invention are directed to conducting polymers are used to produce polymer composites through the addition of graphitic carbon. The concentration of graphitic carbons such as carbon nanotubes is low enough to produce many non-percolated networks of graphitic carbons. Potential commercial applications include self-powered energy harvesting units operated by any type and grade heat including body heat and waste heat. Embodiments of the invention are also directed to a process for a thermoelectric nanocomposite thin film comprising organic conducting polymers and organic conducting nanomaterials.
