柔性电子材料与器件在可穿戴传感领域的发展现状、挑战与创新策略OA北大核心CSTPCD

Wearable materials and devices are developing toward flexibility,lightness,imperceptibility,intelligence,and long-term wearability to meet the personalized needs such as physiological and psychological demands of human body. This trend brought innovation to the field of sports and health monitoring,receiving extensive attention from the academic and industrial communities. However,while meeting the individualized development needs of the human body,wearable flexible materials and devices also face challenges in terms of mechanical robustness,signal stability,soft-hard interface connection,and biocompatibility. Therefore,this review aims to discuss the materials,structures,and fabrication processes for constructing wearable flexible materials and devices from the perspective of practical sports and health monitoring needs,and proposes the major challenging factors and their solutions in terms of mechanical,electrical,and biological performance. Finally,this paper predicts the future development directions of wearable flexible electronic materials and devices,including fully flexible integration,enhanced mechanical robustness,high-precision signal decoupling and recognition,stability,and sensitivity of monitoring,rapid responsiveness,ultra-thin imperceptible design,multimodal signal processing,as well as intelligent adaptive feedback.
