AI Technical Summary

Problems solved by technology

Such gel based electrodes cannot be adapted to clothing as re-usable sensors.
Plane conductive textile based electrodes do not form a good quality contact and are susceptible to ambient noise such as 50 / 60 Hz.
These materials are not compatible to large scale textile manufacturing.
Further, gold nanowires and carbon nanotubes cannot withstand the abrasive force encountered in a typical wearable application and tend to collapse.

Embodiment Construction

[0020]The present disclosure provides a novel textile based nanostructured sensors that can be fabricated by using specially designed high throughput processes that are compatible with existing textile manufacturing technology.

[0021]Nanostructured textile-based dry sensors and electrodes are better suited for long term monitoring and measurement of biopotential signals such as electrocardiography (ECG or EKG), electroencephalography (EEG), electrooculography (EOG), electromyography (EMG) and bioimpedance with very low baseline noise, because of their improved sensitivity and ability to perform adequately with the natural moisture level of skin. Such textile based electrodes can be seamlessly integrated into garments of daily use such as vests, brassieres, bed sheets, wrist band, head band, chest band, arm band, gloves, and socks. In combination with state of the art embedded wireless network devices that can communicate with smart phone, laptop or directly to a remote server through...

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.

Description

[0001]The present application claims priority to U.S.S.N. 62 / 291088 filed Feb. 4, 2016, U.S. Ser. No. 14 / 995,334, filed Jan. 14, 2016, and U.S.S.N. 62 / 104,686, filed Jan. 16, 2015, the entire disclosures of which are hereby incorporated by reference.[0002]The present disclosure relates generally to large scale manufacturing of textile sensors and specifically to hybrid nanostructured textile sensors.BACKGROUND[0003]Unobtrusive health monitoring is highly beneficial for maintaining health and independence of high risk and chronic disease patients. Intelligent wearable sensor systems with simple installation, minimal maintenance and user involvement can be the best method for ubiquitous health monitoring.[0004]Wearable sensor systems in form of smart clothing can contribute tremendously to self-defined and autonomous (at home) living with improved quality of life. They are cost effective and provide lightweight simple technical infrastructure. Existing ambulatory recording equipment r...
