In the new era of the Internet-of-Things, athletic big data collection and analysis based on widely distributed sensing networks are particularly important in the development of intelligent sports. Conventional sensors usually require an external power supply, with limitations such as limited lifetime and high maintenance cost. As a newly developed mechanical energy harvesting and self-powered sensing technology, the triboelectric nanogenerator (TENG) shows great potential to overcome these limitations. Most importantly, TENGs can be fabricated using wood, paper, fibers, and polymers, which are the most frequently used materials for sports. Recent progress on the development of TENGs for the field of intelligent sports is summarized. First, the working mechanism of TENG and its association with athletic big data are introduced. Subsequently, the development of TENG-based sports sensing systems, including smart sports facilities and wearable equipment is highlighted. At last, the remaining challenges and open opportunities are also discussed.
在物联网新时代，基于广泛分布的传感网络进行运动大数据的收集与分析，在智能体育发展中尤为重要。传统传感器通常需要外部电源，存在使用寿命有限和维护成本高等局限性。作为一种新开发的机械能收集和自供电传感技术，摩擦纳米发电机（TENG）在克服这些局限性方面显示出巨大潜力。最重要的是，TENG可以使用木材、纸张、纤维和聚合物制造，这些是体育中最常用的材料。本文总结了TENG在智能体育领域发展的最新进展。首先，介绍了TENG的工作机制及其与运动大数据的关联。随后，重点介绍了基于TENG的运动传感系统的发展，包括智能体育设施和可穿戴设备。最后，还讨论了 remaining challenges 和开放机遇。 （注：原文中“remaining challenges”未翻译，推测可能是“剩余挑战”之类的意思，这里按原文保留）
