  • Publication number: 20210404082
    Abstract: A process for the large scale manufacturing of vertically standing hybrid nanometer-scale structures of different geometries, including fractal architecture made of flexible materials, on a flexible substrate including textiles is disclosed. The nanometer-scale structures increase the surface area of the substrate. The nanometer-scale structures may be coated with materials that are sensitive to various physical parameters or chemicals such as but not limited to temperature, humidity, pressure, atmospheric pressure, 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 nanometer-scale structure and substrate with a material which can be used to sense physical parameters and chemicals as listed previously.
