摘要：
Wearable flexible electronics have garnered significant research interest due to their extensive applications in human motion sensing, health monitoring, and human–computer interaction. Among these, flexible strain sensors that effectively convert external stimuli into electrical signals are crucial for wearable electronic devices. Bacterial cellulose (BC), characterized by its rich hydroxyl groups and unique three-dimensional porous network structure, exhibits excellent biocompatibility, flexibility, and mechanical strength, making it an ideal candidate for high-performance wearable strain sensors as a base material or reinforcing agent. In recent years, numerous studies have focused on BC-based strain sensors, highlighting the urgent need for a comprehensive review of the latest research progress in this field. This review delves into the preparation methods and key properties of bacterial cellulose, categorizing the advancements in BC-based wearable strain sensors according to the type of conductive fillers used. Furthermore, it analyzes the role of BC in enhancing the critical performance metrics of strain sensors, summarizing its contributions to sensitivity, stretchability, linearity, and dynamic durability. Considering the unique three-dimensional porous structure of BC, high mechanical strength, and excellent flexibility, it holds vast potential for applications in wearable strain sensors, including motion detection, health monitoring, and human–computer interaction. © 2025
