Following the rapid development of lightweight and flexible smart electronic products, providing energy for these electronics has become a hot research topic. The human body produces considerable mechanical and thermal energy during daily activities, which could be used to power most wearable electronics. In this context, fiber-based energy conversion devices (FBECD) are proposed as candidates for effective conversion of human-body energy into electricity for powering wearable electronics. Herein, functional materials, fiber fabrication techniques, and device design strategies for different classes of FBECD based on piezoelectricity, triboelectricity, electrostaticity, and thermoelectricity are comprehensively reviewed. An overview of fiber-based self-powered systems and sensors according to their superior flexibility and cost-effectiveness is also presented. Finally, the challenges and opportunities in the field of fiber-based energy conversion are discussed.
随着轻巧灵活的智能电子产品的快速发展，为这些电子产品供电成为了一个热门的研究课题。人体在日常活动中会产生可观的机械能和热能，这些能量可以为大多数可穿戴电子产品提供动力。在此背景下，纤维基能量转换器件（FBECD）被提出来作为将人体能量有效转换为电能为可穿戴电子产品供电的候选器件。本文综述了基于压电、摩擦电、静电和热电原理的不同类型 FBECD 的功能材料、纤维制造技术和器件设计策略。还根据其优越的灵活性和成本效益，对纤维基自供电系统和传感器进行了概述。最后，讨论了纤维基能量转换领域面临的挑战和机遇。
