Emerging Trends in 2D Flexible Electronics

Abstract

AbstractPotential for integrated flexible electronics has been shown for 2D materials with atomically thin layers and dangling‐bond‐free surfaces. Strain engineering is a fascinating technique for tuning or controlling the electronic and optical properties of 2D materials. In the review article, an effort to condense the most recent and promising approaches that can be used to create flexible nanoelectronic and optoelectronic devices in the future and expand their range of useful applications is made. In order to investigate their electrical behavior, the majority of the devices are created using chemical vapor deposition (CVD) or mechanical exfoliation of ultrathin 2D TMD materials. This makes it possible to develop flexible piezo‐phototronic photodetectors, self‐powered sensors, and wearable and implantable devices with higher strain tolerance. On the basis of 2D TMDs materials, a comparison of the performance and characteristics of 2D flexible electronic devices is also carried out. In order to advance the development of wearable and implantable electronics with greater strain tolerance for health monitoring and usher in a new era of flexible technologies, this overview of recent research on 2D flexible electronics based on nanomaterials is intended to aid in the advancement of the field. Finally, it summarizes the current challenges and opportunities.
