The triboelectric nanogenerator (TENG) as a promising energy scavenging technology has been utilized to convert ambient mechanical energy into electric energy for meeting ever‐increasing energy consumption and the need for sustainable energy in modern life. However, the electric energy generated by the conventional TENG based on coupling the contact electrification and electrostatic induction is pulsed alternating current, which requires rectification measures to obtain the direct current (DC) power suitable for storing and driving electronic equipment, resulting in the limitation of its portability and energy utilization efficiency. Through the use of new materials and structures, novel direct current triboelectric nanogenerators (DC‐TENGs) with constant DC output characteristics provide an intelligent solution. Here, the development of DC‐TENG is reviewed, focusing on the working mechanisms of DC‐TENG based on various strategies. The important factors affecting the outputs and the main applications of DC‐TENGs are summarized. Moreover, the possible challenges and future direction for DC‐TENGs are also discussed.

直流摩擦电纳米发电机

摩擦电纳米发电机（TENG）作为一种有前途的能量清除技术，已被用于将周围的机械能转化为电能，以满足不断增长的能源消耗和现代生活中对可持续能源的需求。然而，传统的TENG基于接触带电和静电感应的耦合而产生的电能是脉冲交流电，这需要整流措施来获得适合于存储和驱动电子设备的直流电，从而限制了其使用寿命。其便携性和能源利用效率。通过使用新材料和结构，具有恒定直流输出特性的新型直流摩擦电纳米发电机（DC-TENG）提供了一种智能解决方案。这里，回顾了DC-TENG的发展，重点关注基于各种策略的DC-TENG的工作机制。总结了影响DC-TENG的输出的重要因素和主要应用。此外，还讨论了DC-TENG的可能挑战和未来方向。
