Abstract The advent of artificial intelligence (AI) has sparked considerable interest in intelligence within human society. Flexible sensors, a pivotal component of the interconnection between the physical and digital worlds, have undergone a metamorphosis from a single sensing function to sophisticated integrated systems. Flexible capacitive pressure sensors have emerged as a prominent category of flexible pressure sensors due to their high sensitivity, low power consumption, high stability, easy integration, etc., which have significant potential in the fields of human-computer interaction, health monitoring, and so on. Despite the significant progress that has been made in the field of flexible capacitive pressure sensors, the trade-off between the sensitivity and the detection range remains a critical challenge in practical application. In this paper, the latest developments in the exploitation of flexible capacitive pressure sensors are reviewed in terms of sensing mechanism, selection of sensing materials, structural design and their advanced applications. First, based on these sensing mechanisms, the selection of composition materials in flexible capacitive pressure sensors to implement the optimization of sensing performance is emphatically presented. Second, the well-designed structures applied to the composition analysis are also overviewed, such as the surface microstructure, porous structure, and multilayer structure. Finally, the potential application scenarios of flexible capacitive pressure sensors in different pressure detection ranges are summarized and prospected.
