“…Importantly, the skin contains the largest amount of sensing receptors to perceive various environmental stimuli that humans encounter, such as pressure, strain, humidity, temperature, and pain ( Figure 1 A). To date, tremendous skin-inspired flexible and stretchable devices have been developed based on our understanding of the human skin’s sensing functions ( Benight et al., 2013 ; Cheng et al., 2019 ; Kim et al, 2011a , 2011b , 2016a ; Lei and Wu, 2018 ; Liang et al., 2013 ; Lipomi et al., 2011 ; Oh et al., 2016 ; Pelrine et al., 2000 ; Sekitani et al., 2008 , 2009 ; Sun et al, 2006 , 2014 ; Ying et al., 2020a , 2020c , 2021b , 2021c ; Yu et al., 2020d ; Zang et al., 2013 ). These advances have revolutionized wearable electronics and other related fields.…”

Summary Skin-like electronics are developing rapidly to realize a variety of applications such as wearable sensing and soft robotics. Hydrogels, as soft biomaterials, have been studied intensively for skin-like electronic utilities due to their unique features such as softness, wetness, biocompatibility and ionic sensing capability. These features could potentially blur the gap between soft biological systems and hard artificial machines. However, the development of skin-like hydrogel devices is still in its infancy and faces challenges including limited functionality, low ambient stability, poor surface adhesion, and relatively high power consumption (as ionic sensors). This review aims to summarize current development of skin-inspired hydrogel devices to address these challenges. We first conduct an overview of hydrogels and existing strategies to increase their toughness and conductivity. Next, we describe current approaches to leverage hydrogel devices with advanced merits including anti-dehydration, anti-freezing, and adhesion. Thereafter, we highlight state-of-the-art skin-like hydrogel devices for applications including wearable electronics, soft robotics, and energy harvesting. Finally, we conclude and outline the future trends.

“…Thus, other investigators achieved highly efficient recyclable and self-healable performances in PTU CANs when employing relatively hydrophobic segments as reactants instead of PPG. [137][138][139] The mechanism and kinetics of the reconfiguration of PTU networks are affected by the selection of catalysts and thiol structures. As could be expected, PTUs exhibited a faster stress relaxation at higher catalyst concentrations of DBTDL.…”
