摘　　要：Wearable bioelectronics have gained significant attention since they may play a role in transforming current healthcare from a reactive and disease-centric model to a personalized one with a focus on disease prevention and health promotion[1–3].One key building block in this transformation is the advancement in wearable sensory technology,particularly the design and fabrication of highly sensitive strain sensors that can withstand the mechanical deformations associated with bodily movement[4].Furthermore,compared with conventional thin film-based wearable bioelectronics,textile bioelectronics offer enhanced healthcare functionality while maintaining superior breathability,wearing comfort,long service life,environmental stability,and mechanical robustness[5].However,functional fibers,the building blocks of smart textiles,face several developmental challenges.These include the difficulty of loading active materials onto the small and curved surfaces of fibers,the mechanical mismatch between fillers and elastomers which often leads to reduced durability,the need for robust adhesion of sensing materials to prevent wear over time,and the obstacles in generating functional microcracks within conductive materials under strain[1–3].
