Although TENG based on the coupling of triboelectrification and air-breakdown achieves a large direct current (DC) output, material abrasion is a bottleneck for its applications. Here, inspired by primary cell and its DC signal output characteristics, we propose a novel primary cell structure TENG (PC-TENG) based on contact electrification and electrostatic induction, which has multiple working modes, including contact separation mode, freestanding mode and rotation mode. The PC-TENG produces DC output and operates at low surface contact force. It has an ideal effective charge density (1.02 mC m<sup>−2</sup>). Meanwhile, the PC-TENG shows a superior durability with 99% initial output after 100,000 operating cycles. Due to its excellent output performance and durability, a variety of commercial electronic devices are powered by PC-TENG via harvesting wind energy. This work offers a facile and ideal scheme for enhancing the electrical output performance of DC-TENG at low surface contact force and shows a great potential for the energy harvesting applications in IoTs.</p> <p>Highlights:</p> <p>1 A novel structure of the PC-TENG based on triboelectrification and electrostatic induction is designed.<br>2 The PC-TENG produce ideal direct current output for driving small electronic devices directly even at low surface contact force.<br>3 The novel PC-TENG owns a high durability and high output performance due to low wear of materials.<br>4 The R-PC-TENG can efficiently harvest ambient mechanical energy.</p>}, journal={Nano-Micro Letters}, author={Fu, Shaoke and He, Wencong and Wu, Huiyuan and Shan, Chuncai and Du, Yan and Li, Gui and Wang, Ping and Guo, Hengyu and Chen, Jie and Hu, Chenguo}, year={2022}, month={Aug.}, pages={155} }
