Triboelectric Effect-Driven Liquid Metal Actuators

Recent Development in Liquid Metal Materials

“…Bu et al. introduced a liquid metal actuator driven by a triboelectric effect, which was triboelectric nanogenerators (TENS), and precisely controlled the motion of LM [51] . The Coulomb force and inertia effect of friction charge transferred in interdigital electrode, drive LM to make a continuous linear and circular motion, respectively (Figure 5F).…”

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 ).…”

Advancement of Electroadhesion Technology for Intelligent and Self‐Reliant Robotic Applications

“…Apart from insulating liquids, conducting liquid metal droplets can also be moved using this technique which follows the adhesion principle shown similar to Figure 1. [ 138 ]…”
