Liquid‐Metal‐Based Dynamic Thermoregulating and Self‐Powered Electronic Skin

Advanced Functional Materials, Journal Year: 2021, Volume and Issue: 31(26)

Published: April 18, 2021

Abstract Electronic skin (E‐skin) is an emerging and promising human‐machine interface. Besides skin‐like functions of tactile perception stretchability, comfortabilities, including breathability, moisture permeability, softness, thermoregulating ability are, also crucial factors for E‐skins. Thermoregulation one the most important roles human skin. People can feel comfortable when their skins are regulated at a certain range temperature. Moreover, it dynamic process according to surrounding Current E‐skins do not have function dynamically regulating Here, E‐skin (TE‐skin) based on liquid metal as phase change material with its melting point in temperature reported. Compared conventional E‐skins, TE‐skin termoregulate through change. Combining principle triboelectric nanogenerator, able act self‐powered sensor. Based TE‐skin, intelligent dialing communications system further developed, which be used call cellphone For first time, this study introduces concept could open up new opportunities developments.

Hydrogels as Soft Ionic Conductors in Flexible and Wearable Triboelectric Nanogenerators

Advanced Science, Journal Year: 2022, Volume and Issue: 9(11)

Published: Feb. 20, 2022

Flexible triboelectric nanogenerators (TENGs) have attracted increasing interest since their advent in 2012. In comparison with other flexible electrodes, hydrogels possess transparency, stretchability, biocompatibility, and tunable ionic conductivity, which together provide great potential as current collectors TENGs for wearable applications. The development of hydrogel-based (H-TENGs) is currently a burgeoning field but research efforts lagged behind those common TENGs. order to spur this important area, comprehensive review that summarizes recent advances challenges H-TENGs will be very useful researchers engineers emerging field. Herein, the advantages types soft conductors are presented, followed by detailed descriptions advanced functions, enhanced output performance, well applications H-TENGs. Finally, prospects discussed.
