Low cost and Flexible Graphene Oxide-Based Paper sensor for ultraviolet and sunlight monitoring

Abstract

The enormous effect of ultraviolet (UV) radiation on human beings has sparked intense interest in the development of new sensor technologies to effectively monitor UV and solar exposure. Here, a novel low-cost and flexible Graphene Oxide (GO) paper-based sensor that is capable of detecting the intensity of UV radiation is described. Employing a novel low-cost fabrication technique, GO is implemented in the structure of normal printing paper, cellulose. The impact of the exposure of UV radiation and solar simulator on the GO paper sensor is to be investigated by color intensity analysis and structural characterization tools. Through a simple change in color, the sensor has offered a unique capability to estimate UV intensity. Therefore, users can easily measure the intensity or amount of UV dose they received without the demand of an additional tool. An Artificial Intelligence (AI) application was employed as an additional interface to measure and show the color intensity results in a digital display. The disposable paper-based UV sensor has the features of being cost-effective, simple, made of biodegradable materials, safe, and flexible, making the device a potential candidate for various sensing applications. This work is the first to report on the significant potential of the flexible GO based paper sensors for sensing applications.
