Network Topology Optimization of Triboelectric Nanogenerators for Effectively Harvesting Ocean Wave Energy

“…In 2012, Wang's group invented the triboelectric nanogenerator (TENG) based on contact electrification and electrostatic induction ( Li et al, 2020a , 2020b ; Wang, 2013 ). With the gifted advantages such as simple structure, abundant material options, and low fabrication cost ( Wang, 2014 ; Wang et al., 2015 ; Zhang et al., 2014 ; Zhao et al., 2019 ), the TENGs have made remarkable achievements in the application field of micropower/nanopower sources ( Ahmed et al., 2020 ; Chandrasekhar et al., 2017 ; Deng et al., 2020 ; Jin et al., 2020 ; Liu et al., 2020a ; Lu et al., 2019 ; Quan et al., 2015 ; Šutka et al., 2020 ; Yan et al., 2020 ; Yang et al., 2013 , 2014 ; Zou et al., 2020 ), self-powered sensors ( Bu et al, 2018a , 2018b ; Fu et al., 2017 ; Guo et al., 2018 ; Meng et al., 2020 ; Pang et al., 2015 ; Su et al., 2020a , 2020b ; Wang et al., 2018a ; Zhou et al., 2020b , 2020c ), high-voltage power sources ( Bu et al., 2019 ; Fan et al., 2015 ; Nie et al., 2018 ; Yang et al., 2019a ), and large-scale blue energy ( Chen et al., 2020b ; Liang et al., 2019 ; Rodrigues et al., 2020 ; Xu et al, 2017 , 2018 ; Yang et al., 2019b ; Zhang et al., 2016a ), which is to harvest the low frequency, irregular, and multidirectional water wave energy. Recently, some remarkable works have been developed to improve the performance of TENGs ( Liu et al., 2020b , 2020c ; Wang et al., 2018b ).…”

Leverage Surface Chemistry for High-Performance Triboelectric Nanogenerators

“…The rapid development of wearable and portable electronic devices is greatly revolutionizing our conventional means of energy generation and consumption (Gubbi et al, 2013 ; Lee and Lee, 2015 ; Zhou et al, 2020a ; Zou et al, 2020 ). Miniaturized energy sources with high portability and sustainability are eagerly desired for powering billions of distributed devices in the era of the Internet of Things (Bai et al, 2014 ; Yang et al, 2015 ; Lin et al, 2017 ; Xu et al, 2017 ; Bedi et al, 2018 ; Wang, 2019 ).…”
