Printed 2D Material‐Based Flexible Memory Devices

Printed flexible nonvolatile memory devices are responsible for rapid change of electronics through their inherent properties of mechanical flexibility, lightweight, cost‐effectiveness, and biocompatibility in storing data. These devices serve as essential data storage solutions for emerging technologies, such as wearable electronics, IoT systems, flexible displays, nanoelectronics, and robotics. Two‐dimensional materials such as graphene, graphene oxide (GO), transition metal dichalcogenides such as molybdenum disulfide (MoS 2 ), and hexagonal boron nitride (h‐BN) offer unique electrical, mechanical, and interfacial properties that are highly attractive for resistive switching devices fabricated on flexible substrates using printed techniques or conventional fabrication methods. This review article intends to highlight the latest advancements in printing techniques including inkjet, aerosol jet, and electrohydrodynamic printing for 2D material‐based flexible memory devices, as they have demonstrated potential and are being researched widely in recent times. In addition, the challenges related to printed flexible memory like large‐scale integration for industrial applications and future trends of flexible memory are discussed as well in this article.
