“…Moreover, motions of the neck with continuous movements can also be precisely recorded (Figure l). Therefore, these strain sensors display high sensitivity with strain, temperature, and pressure, as well as rapid response time, self-healability, and wide sensing range, which provides the possibility of application in multifunctional wearable sensors. − …”

Traditional luminescent ionogels often suffer from poor mechanical properties and a lack of recyclability and regeneration, which limits their further application and sustainable development. Herein, a luminescent ionogel with strong mechanical properties and good recyclability has been designed and fabricated by introducing dynamic coordination bonds via in situ one-step crosslinking of acrylic acid in ionic liquid of 1-ethyl-3methylimidazolium diethylphosphate by zinc dimethacrylate. Due to the special crosslinking of dynamic coordination bonds along with the hydrogen bond interaction, the as-prepared ionogel displays excellent stretchability and toughness, good self-adhesiveness, fast self-healability, and recyclability. Interestingly, the obtained ionogels exhibit tunable photoluminescence caused by the crosslink-enhanced emission (CEE) effect from the coordination bonds. Importantly, ionogels can be applied in information storage, information encryption, anti-counterfeiting due to their simple and in situ preparation method, and their special fluorescence performances. Moreover, an ionogel-based wearable sensor has rapid response time and a high gauge factor of 3.22 within a wide strain range from 1 to 700%, which can monitor various human movements accurately from subtle to large-scale motions. This paper offers a promising way to fabricate sustainable functional ionic liquid-based composites with CEE characteristics via an in situ onestep polymerization method.

“…Therefore, the ability of ionogels to exhibit predictable and reliable thermal properties made them promising materials for use in a wide range of temperature sensing applications. Compared with ionogel-based sensors with a relatively low solid content reported in recent years (Figure 6h), [11,[43][44][45][46][47][48][49][50][51] the resulting I-3% exhibited excellent mechanical and applied performance in fracture strength, stretchability, reconstruction, and high GF among the ionogels.…”

Ionogels have become a popular material in flexible electronics and soft robotics based on their excellent ionic conductivity, environmental tolerance, and electrochemical stability. However, it remains a challenge to develop an ionogel integrated with high strength, toughness, self‐healing, and adhesion. Herein, a novel strategy is established to design a high‐strength (0.97 MPa) and tensile (980%), excellent crack insensitivity, self‐healing ionogel based on the cosolvent method. By virtue of differential interactions between the specific polymer and various ionic liquids with gradient polarity, cosolvent systems are employed to achieve high‐performance ionogels by a simple one‐step polymerization. Gel permeation chromatography, atomic force microscopy, time‐domain nuclear magnetism, and density functional theoretical calculation are used to analyze the reasons. Microphase separation can be induced by hydrone or stretching to enhance strength of the ionogel. Therefore, ionogels can be assembled as strain and temperature sensors to monitor human movement and person's body temperature with a low detection threshold (0.1 °C) in extreme environments. This concept creates a new path to achieve soft materials with high performance, and provide a prospective strategy to regulate the in situ microphase change and performance of the resulting ionogel via the one‐step polymerization.

“…The larger the hysteresis, the more dynamic keys that have not been recovered in the first loadunload cycle, and therefore the longer recovery time will be required. 60 Besides, the failure of rapid self-recovery will make the skin-like hydrogels unable to produce stable and consistent electrical signals in cyclic continuous detection. 61,62 Given the quick recovery time of the skin and the precise nature of the signal transmission, it is also worth considering how not to introduce too much lag in the toughening process for the skinlike hydrogels.…”
