Novel Flexible Disposable Paper-Based Graphene Oxide Memristor

Abstract

The development of flexible memristor devices is a nascent research area with great potential to revolutionize wearable electronics. A few flexible memristor devices with proven functionality and reliability have been introduced in the literature. This work describes the development of a novel paper memristor device, employing a novel low-cost fabrication technique. The device consists of three layers: top electrode, active material, and bottom electrode. All three layers are made of the same materials specifically cellulose and reduced graphene oxide with different concentrations. Detailed I-V measurements are carried out to verify the resistive switching property of the device. Because it is made entirely of paper, it is hydrophilic, which means that liquids may flow freely through its porous structure. This simple capillary action eliminates the need for additional mechanical pumping structures, making the device a promising candidate for a variety of applications, such as dehydration or glucose level detection. This work is the first to report on the significant potential of flexible GO-based paper memristor devices for emerging wearable electronics and sensing applications. Using paper only to realize memristors has the advantages of being compact, affordable, effective, biocompatible, and conveniently disposable, making it suitable for a wide range of applications.
