Large scale manufacturing of hybrid nanostructured textile sensors

a nano-structured textile and nano-technology, applied in spinnerette packs, conductive pattern formation, liquid/solution decomposition chemical coatings, etc., can solve the problems of incompatibility of materials with large-scale textile manufacturing, inability to adapt gel-based electrodes to clothing as re-usable sensors, and inability to form good quality contact between plane-conductive textile-based electrodes,

Abstract

A process for the large-scale manufacturing vertically standing hybrid nanometer scale structures of different geometries including fractal architecture of nanostructure within a nano / micro structures made of flexible materials, on a flexible substrate including textiles is disclosed. The structures increase the surface area of the substrate. The structures maybe coated with materials that are sensitive to various physical parameters or chemicals such as but not limited to humidity, pressure, atmospheric pressure, and electromagnetic signals originating from biological or non-biological sources, volatile gases and pH. The increased surface area achieved through the disclosed process is intended to improve the sensitivity of the sensors formed by coating of the structure and substrate with a material which can be used to sense physical parameters and chemicals as listed previously. An embodiment with the structures on a textile substrate coated with a conductive, malleable and bio-compatible sensing material for use as a biopotential measurement electrode is provided.
