| Abstract: |
Graphene‐based flexible sensors have been widely investigated for wearable electronics, healthcare monitoring, and emerging soft robotic systems. Despite substantial progress, their overall performance is still constrained by the coupled limitations in sensitivity, mechanical reliability, and effective sensing range. This review discusses recent advances in addressing these issues through microstructure design and interface engineering. Carefully tailored microstructures, such as bio‐inspired geometries, interconnected porous frameworks, and deliberately introduced microcrack features, are shown to play a decisive role in regulating stress distribution and signal transduction, thereby enhancing device responsiveness under diverse stimuli. In parallel, interface engineering, including plasma‐assisted surface modification and hybridization with functional nanomaterials, has been demonstrated to improve charge transport behavior, structural stability, and sensing selectivity. By linking structural design and interfacial regulation with sensing performance, this review aims to clarify the underlying enhancement mechanisms and to offer useful references for the development of high‐performance graphene‐based flexible sensors.
