“…Reproduced with permission: Copyright 2020, Elsevier 39 with a supramolecular crosslinked structure. 20 The recyclable ionic polymer was a co-polymerized product between an ionic conductive monomer (imidazolium acetate with vinyl group, [VEIm][Ac]) and a nonconductive monomer with quadruple hydrogen bonding motif (UHH) (Figure 5A). As well studied, the conductivities of [VEIm][Ac] and its polymerized product were both thermal sensitive, indicating the sought-for feature of producing thermometers.…”

“…18,19 Without involving particular sensing materials, some cases reported that fully recyclable electronic sensors might be solely formulated by intrinsically conductive polymers. 20 From a sufficient survey, this research field is just at the emerging stage without specific review papers or progressive reports. Considering its importance and necessity, we think it is timely to present a minireview on this research frontier to summarize the recent progresses relevant to those fully recyclable electronic sensors and hopefully offer new inspirations in the electronic sensing field.…”

The increasing number of electronic sensors after their disposal is leading to severe environmental threatens due to the release of heavy metals or other nonrecyclable semiconductors in sensing units and have raised worldwide interest in the design of electronic sensors with longer-term service life in order to reduce the discharge of electrical pollutants. From this point of view, there have been a great number of examples relevant to electronic sensors with self-healing or recyclable properties. Unlike the enormous studies paid to selfhealing electronic sensors, a limited number of fully recyclable sensors have been exploited and there is no review article relevant to this topic so far. This minireview aims to summarize the recent progresses of electronic sensors that could be shredded and reshaped with the assistance of recyclable polymers.Two types of fully recyclable electronic sensors are mainly focused, including blended type via blending sensing conductors in the polymer matrix and intrinsic type composed of sensing polymers. According to their classification, we specifically demonstrate the basic design principle, recycling procedure, and sensing performance of those different types of recyclable electronic sensors. At last, a brief discussion regarding the remaining challenges and future perspectives of this new research area is delivered which hopefully provides inspirations to develop more fully recyclable electronic sensors with versatile functions.

“…New strategies combining conductive groups (as found in polyelectrolytes) and soft groups with reversible bonds, gives both ionic conductivity and self‐healing properties. [ 67 ] This might be similar to composites in which the filler is covalently connected to the matrix or to the healable semiconductive copolymers that contain both conjugated and supramolecular (dynamic) parts. [ 68 ] Such polymers would be highly advantageous as they would eliminate the mismatch and the repulsions that exist between different phases in the composite methods.…”

The demand for interfacing electronics in everyday life is rapidly accelerating, with an ever‐growing number of applications in wearable electronics and electronic skins for robotics, prosthetics, and other purposes. Soft sensors that efficiently detect environmental or biological/physiological stimuli have been extensively studied due to their essential role in creating the necessary interfaces for these applications. Unfortunately, due to their natural softness, these sensors are highly sensitive to structural and mechanical damage. The integration of natural properties, such as self‐healing, into these systems should improve their reliability, stability, and long‐term performance. Recent studies on self‐healing soft sensors for varying chemical and physical parameters are herein reviewed. In addition, contemporary studies on material design, device structure, and fabrication methods for sensing platforms are also discussed. Finally, the main challenges and future perspectives in this field are introduced, while focusing on the most promising examples and directions already reported.

“…For example, the health conditions of human body are expected to be monitored in order to facilitate the hospital or healthcare machines to make proper actions. [84,85] To achieve this objective, sensors need to be soft enough to: 1) adapt the modulus of human tissues so as to eliminate the discomfort and 2) endure the repeated stretching and bending deformation led by the motion of joints. Soft electronic sensors based on liquid conductors are considered as an intriguing choice to satisfy these requirements that are restraining traditional sensors.…”

Soft electronics is an emerging field that is lending great convenience to daily life. Soft electronics have shown great potentials in health monitoring, soft robotics, the Internet of Things, and so forth. Though soft electronics based on solid conductors have been intensively investigated and some considerable progress has been achieved, the intrinsic shortcomings of solid conductors are becoming the Achilles’ heel of soft electronics. Fortunately, many of the disadvantages of solid conductors can be offset by liquid conductors. Following the attractive advantages of liquid materials, in particular high flexibility, infinite deformability, self‐healing, and ease of doping/being doped, this review article summarizes a history of soft electronics based on liquid conductors and introduces the most up‐to‐date liquid conducting materials together with their representative featured functions. Particular applications in sensors, batteries, supercapacitors, thermoelectric conversion, and even memory devices are discussed in detail to intuitively emphasize how liquid conductors benefit soft electronics. In addition, limitations of liquid conductors are also discussed, as well as the key challenges and some innovative strategies to overcome them. Finally, future perspectives are put forward to develop soft electronics that are fully composed of liquid circuits.
