Carbon Nanotube-Based Flexible and Stretchable Electronics

Abstract

Flexible and stretchable electronics hold great promise for wearable devices and health monitoring systems owing to their mechanical conformability, light weight, and seamless integration capabilities. Nevertheless, achieving high electrical performance while retaining flexibility and operational stability remains a considerable challenge. Among various candidate materials, carbon nanotubes (CNTs) have garnered significant attention due to their exceptional carrier mobility, inherent mechanical flexibility, and compatibility with low-temperature fabrication processes. This article provides a comprehensive overview of recent progress in flexible and stretchable electronics, focusing specifically on advances in CNT-based thin-film transistors and integrated circuits. Furthermore, it examines emerging applications of CNTs in artificial neuromorphic systems and soft sensors, underscoring their potential to enable next-generation soft electronic technologies.
