“…In recent years, with the rapid growth of intelligent technology such as the internet of things and human-machine interface, a variety of devices have been developed for air quality monitoring [1] , [2] , [3] , [4] , disease screening and diagnosis [5] , [6] , [7] , [8] , human motion detecting [9] , [10] , [11] , and so on. Humidity is one of the essential indexes of air, which is important for industrial and agricultural production and our daily life.…”

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

“…Compared to other energy harvesting approaches, TENG has several advantages: light weight, low cost, flexible structures, extensive material selection, and great efficiency at low operating frequencies, all of which make TENGs one of the mainstream power supplies for self-powered devices (Jing et al, 2014 ; Yang W. et al, 2014a , b ; Kuang et al, 2015 ; Lin et al, 2016 ; Liu R. et al, 2018 ; Chu et al, 2020 ; Pu et al, 2020a ). TENGs is feasible for driving various electronic devices, ranging from light-emitting diodes (LEDs) (Yang et al, 2013d ; Lin et al, 2014 ; Chun et al, 2015 ; Kanik et al, 2015 ; Mao et al, 2015 ; Wu et al, 2016 ) to cell phones (Wang et al, 2012 ; Zhu et al, 2014c ) and from a large number of bio-sensors (Fan et al, 2015 ; Wen et al, 2015 ; Cai et al, 2018 ; Su et al, 2018 , 2020a , b ; Davoodi et al, 2020 ; Meng et al, 2020 ) to pacemakers (Zheng Q. et al, 2014 ). This shows showing their remarkable compatibility with a wide range of application in different settings, displaying that plentiful possibilities are remaining to be further explored (Wang, 2014 ; Hinchet et al, 2015 ; Wang S. et al, 2015 ; Zhang et al, 2015 ; Zhu et al, 2015 ; Zhang B. et al, 2016 ; Pu et al, 2020b ).…”
