Synthesis methods of flexible materials for sensing

Abstract

Owing to their unique bendable and stretchable properties, flexible materials have demonstrated broad application prospects across diverse fields. Meanwhile, electrochemical sensors have been extensively utilized due to their advantages of low cost and operational convenience. In recent years, the integration of flexible materials with sensing technologies has emerged as a significant research trend. This review comprehensively summarizes state-of-the-art synthesis methods for flexible materials employed in electrical flexible sensors, with particular emphasis on hydrogels, ionogels, and liquid-free solid ionic elastomers, along with performance optimization strategies tailored to specific functional requirements. Furthermore, the potential applications of flexible sensors are systematically discussed. Finally, the current technological limitations of flexible sensors are critically analyzed in the context of market demands, and promising future research directions are proposed.
