The rapid development of flexible sensor technology has made arrays a key research area in various applications due to their exceptional flexibility, wearability, and large-area-sensing capabilities. These can precisely monitor physical parameters like pressure strain complex environments, making them highly beneficial for sectors such as smart wearables, robotic tactile sensing, health monitoring, electronics. This paper reviews the fabrication processes, operational principles, common materials used sensors, explores application different materials, outlines two conventional preparation methods. It also presents real-world examples large-area arrays. Fabrication techniques include 3D printing, screen laser etching, magnetron sputtering, molding, each influencing performance ways. Flexible sensors typically operate based on resistive capacitive mechanisms, with structural designs (e.g., sandwich fork-finger) affecting integration, recovery, processing complexity. careful selection materials—especially substrates, electrodes, sensing materials—is crucial efficacy. Despite significant progress design application, challenges remain, particularly mass production, wireless real-time data processing, long-term stability. To improve production feasibility, optimizing reducing material costs, incorporating automated lines are essential scalability defect reduction. For enhancing energy efficiency through low-power communication protocols addressing signal interference stability critical seamless operation. Real-time requires innovative solutions edge computing machine learning algorithms, ensuring low-latency, high-accuracy interpretation while preserving flexibility Finally, environmental adaptability demands new protective coatings withstand harsh conditions. Ongoing overcoming these challenges, that meet needs diverse remaining cost-effective reliable.
