Flexible Electronic Devices Based on Two-Dimensional Material/Polymer Composites

Abstract

The new generation of electronic devices is incorporating mechanical flexibility into their design, a trend that demands large-area, ultra-thin functional materials that are both energy-efficient and economically viable. The emergence of two-dimensional materials has ushered in a new era of integrated, flexible technology, surpassing the capabilities of traditional semiconductors. Furthermore, 2D materials are highly valuable for advancing a wide range of emerging fields, including wireless health monitorin g systems, flexible bioelectronics, and origami-inspired unconventional device architectures, all of which are suitable for challenging applications. This review examines the technological progress and fundamental aspects of 2D material -based flexible devices. This article will systematically summarize the applications of these devices in various areas. Subsequently, this paper focuses on elaborating the applications of such devices from three core perspectives: flexible sensors, flexible displays, and bio-integrated soft electronics. These devices offer promising prospects in fields such as health monitoring, human -machine interaction, and medical diagnosis. Finally, the paper discusses current challenges and their solutions.
