Theoretical study of contact-mode triboelectric nanogenerators as an effective power source
Simiao Niu,Sihong Wang,Long Lin,Ying Liu,Yu Sheng Zhou,Youfan Hu,Zhong Lin Wang,Zhong Lin Wang +7 more
TL;DR: In this paper, a theoretical model for contact-mode TENGs was constructed based on the theoretical model, its real-time output characteristics and the relationship between the optimum resistance and TENG parameters were derived.
Journal ArticleDOI
Pyroelectric nanogenerators for harvesting thermoelectric energy.
Ya Yang,Wenxi Guo,Ken C. Pradel,Guang Zhu,Yu Sheng Zhou,Yan Zhang,Youfan Hu,Long Lin,Zhong Lin Wang,Zhong Lin Wang +9 more
TL;DR: This study experimentally demonstrates the first application of pyroelectric ZnO nanowire arrays for converting heat energy into electricity and has the potential of using pyro electric nanowires to convert wasted energy into Electricity for powering nanodevices.
Journal ArticleDOI
Theory of Sliding‐Mode Triboelectric Nanogenerators
Simiao Niu,Ying Liu,Sihong Wang,Long Lin,Yu Sheng Zhou,Youfan Hu,Zhong Lin Wang,Zhong Lin Wang +7 more
TL;DR: In this paper, a theoretical model for the sliding-mode TENG is presented, where the finite element method was utilized to characterize the distributions of electric potential, electric field, and charges on the metal electrodes of the TENG.
Journal ArticleDOI
Gigantic enhancement in response and reset time of ZnO UV nanosensor by utilizing Schottky contact and surface functionalization
Jun Zhou,Yudong Gu,Youfan Hu,Wenjie Mai,Ping-Hung Yeh,Gang Bao,Ashok K. Sood,Dennis L. Polla,Zhong Lin Wang +8 more
TL;DR: By utilizing Schottky contact instead of Ohmic contact in device fabrication, the UV sensitivity of the ZnO nanowire nanosensor has been improved by four orders of magnitude, and the reset time has been drastically reduced.
Journal ArticleDOI
Theoretical Investigation and Structural Optimization of Single-Electrode Triboelectric Nanogenerators
Simiao Niu,Ying Liu,Sihong Wang,Long Lin,Yu Sheng Zhou,Youfan Hu,Zhong Lin Wang,Zhong Lin Wang +7 more
TL;DR: In this article, a theoretical model of SETENGs with in-depth interpretation and analysis of their working principle is presented, and the impacts of two important structural parameters, that is, the electrode gap distance and the area size, on the output performance are theoretically investigated.
