“…In addition to the MOS/rGO nanocomposites used for sensing studies [ [184] , [185] , [186] ], many MOS/conducting polymer (CP) composites have been used for such purposes. CPs such as polyaniline (PANI), polythiophene (PTh) and polypyrrole (PPy) are the most common polymers for RT gas-sensing studies due to their unique electrical and optical characteristics, low cost, ease of fabrication, and flexibility [ [187] , [188] , [189] ].…”

With the tremendous advances in technology, gas-sensing devices are being popularly used in many distinct areas, including indoor environments, industries, aviation, and detectors for various toxic domestic gases and vapors. Even though the most popular type of gas sensor, namely, resistive-based gas sensors, have many advantages over other types of gas sensors, their high working temperatures lead to high energy consumption, thereby limiting their practical applications, especially in mobile and portable devices. As possible ways to deal with the high-power consumption of resistance-based sensors, different strategies such as self-heating, MEMS technology, and room-temperature operation using especial morphologies, have been introduced in recent years. In this review, we discuss different types of energy-saving chemisresitive gas sensors and their application in the fields of environmental monitoring. At the end, the review will be concluded by providing a summary, challenges and future perspectives.

“…Smart surfaces have attracted considerable interests because the surface chemistry and surface roughness play an important role in controlling surface wettability (Fang et al, 2010 ; Xu et al, 2013 ; Huang et al, 2017 ; Wei et al, 2017 ). Nowadays, the rapid development of responsive materials has enabled surface chemistry and surface roughness change to switch surface wettability through external stimuli (Xin et al, 2016 ; Wu et al, 2017 ; You et al, 2018 ; Salter and Booth, 2019 ; Zhang et al, 2019c ; Fu et al, 2020 ; Zou et al, 2020 ). Due to the reversible dynamic control capability, tremendous effects have been devoted to developing driving techniques (Yin et al, 2018 ; Liu et al, 2020 ; You et al, 2020 ) such as temperature, light, electric/magnetic fields, chemicals, and mechanical motion (Han et al, 2015a , b , 2016 ; Yong et al, 2015 ).…”

“…As a mask-free and chemical free method, laser processing of graphene has been successfully employed for both the preparation of graphene and the fabrication of graphene-based electronic skins (El-Kady and Kaner, 2014; Kymakis et al, 2014; Han et al, 2015b). Laser processing has been firstly used for the reduction and patterning of chemically derived graphene oxide (GO) (Zhang et al, 2014; Han et al, 2018; You et al, 2018). After laser treatments, the oxygen containing groups (OCGs) on GO sheets can be effectively removed, and therefore the conductivity can be recovered (Xiong et al, 2015; Hong et al, 2016).…”

Graphene is promising for developing soft and flexible electronic skin. However, technologies for graphene processing is still at an early stage, which limits the applications of graphene in advanced electronics. Laser processing technologies permits mask-free and chemical-free patterning of graphene, revealing the potential for developing graphene-based electronics. In this minireview, we overviewed and summarized the recent progresses of laser enabled graphene-based electronic skins. Two typical strategies, laser reduction of graphene oxide (GO) and laser induced graphene (LIG) on polyimide (PI), have been introduced toward the fabrication of graphene electronic skins. The advancement of laser processing technology would push forward the rapid progress of graphene electronic skin.
