“…7, once applying a thin layer of DES hydrogel on the glass substrate, it was then immersed in deionized water at 60 °C for 25 min. After 16 h, the hydrogel over the glass base was fully dissolved, providing excellent degradability in water (Wu et al 2018;Yamada and Toshiyoshi 2018).…”

The flexible hydrogel sensors in the field of artificial intelligence have been widely concerned, which could be applied in medical monitoring, human motion detection, and intelligent robots. However, the integration of the synergistic properties of excellent mechanical properties, temperature sensitivity, adhesion ability and self-healing ability for preparation of hydrogel-type strain sensor is still a challenge. Moreover, how can we recover cumulated sensors without affecting the environment? Herein, a self-healing hydrogel was prepared based on deep eutectic solvent (DES) combined with polyvinyl alcohol (PVA), and cellulose nanocrystals (CNCs), which has the peotential application as wearable strain sensors. The DES network crosslinks PVA/CMC-Na/CNCs through ionic bonds, and the overall network is further linked through physical entanglement and hydrogen bonding interactions. Interestingly, the hydrogel could sensitively detect large or subtle movements (such as finger bending, wrist bending, knee bending, pulse and pronounce), indicating its potential applications in human-computer interaction and personal health monitoring.

“…As a result, they may also decay over time. Yamada and Toshiyoshi (2018) combined ionic liquids (IL) with PVA to develop a water-soluble hydrogel. The developed ionic gel maintained the morphology of the gel while forming the electrical double layer as the ions were suspended in the conjugated polymer network.…”

been widely considered, which possess unique properties including stretchable, self-healable, and interestingly, bio-degradable. [6][7][8][9][10][11][12] However, heightened water loss when left at ambient conditions for a short period of time was a debilitating drawback to the performance, [11] which hindered its ubiquitous application to our daily-lives. [13] To resolve the poor stability of hydrogels, ionic gels (IG), i.e., gels that contain ionic electrolytes (e.g., aqueous solutions of inorganic salts, [14][15][16][17][18] ionic liquids [19][20][21][22][23] and non-aqueous electrolyte salts, [20] offer liquid mobile ions) and polymers (serve as the framework), have gradually attracted research interest. Among the ionic electrolytes, ionic liquid (IL) excels for its comprehensive characteristics of superconductivity, weak-volatility, high electrochemical stability and wide potential window. [24][25][26][27][28][29] When composited with polymers, the superior ion conduction is preserved in the semi-solid state, and the obtained IG can withstand external loads. [30][31][32][33] Thus, various types of sensors have been developed for sensing tensile strain (stretch), [34,35] pressure (touch), [36,37] or torsion (twist). [34] However, most IG sensors are designed to sense only one type of mechanical stimulus; [38][39][40][41] if sensing multiple deformation stimuli is required, the fabrication of the sensor becomes significantly more sophisticated. [7,[42][43][44][45] Therefore, it is of great significance to design a simple sensor that is capable of detecting multiple stimuli, i.e., strain, pressure, and torsion.With the recent, rapid development in wearable electronics, flexible sensors have almost matured to marketability. However, current flexible sensing materials typically incorporate electronconductive carbon, silver or ionic conductive IL as conductive fillers into a polymer matrix. As a result, the color of the developed sensors is either pure black, white or transparent; this selection is monotonous and will not meet the color demands of the customers. This issue is particularly prominent when the sensors are attached to skin or clothing that is externally visible. On the other side, more people begin to consider their fitness levels, and night exercises (e.g., night running) has been escalating in favor by day-shift workers due to their busy days. However, survey has shown that the number of accidents caused by fitness workers' ignorance of their possible physical discomfort and poor lighting in the night are increasing each Recently, flexible sensors have attracted great interest for their promising application in wearable electronics. However, previous mechanical sensors are typically limited to detecting one type of stimulus and monotonous in color, which are not able to meet the sensing nor fashion requirements by customers who will wear them in daily life. Herein, a flexible and stretchable sensor based on highly conductive ionic gel is developed. Different phosphor nanoparticles are uniformly embe...

“…[31] Despite all the advantages, to date no works have applied ILs into secondary transient batteries as their use has mainly been limited to degradable primary Mg batteries, [32] or supercapacitors. [33] In this work we design a transient high transport number Li + conductor for degradable LIBs. Porous membranes comprising a PVA matrix with embedded CNCs are obtained through non-solvent induced phase separation (NIPS) method.…”

Transient batteries play a pivotal role in the development of fully autonomous transient devices, which are designed to degrade after a period of stable operation. Here, a new transient separator‐electrolyte pair is introduced for lithium ion batteries. Cellulose nanocrystals (CNCs) are selectively located onto the nanopores of polyvinyl alcohol membranes, providing mobile ions to interact with the liquid electrolyte. After lithiation of CNCs, membranes with electrolyte uptake of 510 wt%, ionic conductivities of 3.077 mS·cm–1, electrochemical stability of 5.5 V versus Li/Li+, and high Li+ transport numbers are achieved. Using an organic electrolyte, the separators enable stable Li metal deposition with no dendrite growth, delivering 94 mAh·g–1 in Li/LiFePO4 cells at 100 mA·g–1 after 200 cycles. To make the separator‐electrolyte pair transient and non‐toxic, the organic electrolyte is replaced by a biocompatible ionic liquid. As a proof of concept, a fully transient Li/V2O5 cell is assembled, delivering 55 mAh·g–1 after 200 cycles at 100 mA·g–1. Thanks to the reversible Li plating/stripping, dendrite growth suppression, capacity retention, and degradability, these materials hold a bright future in the uptake of circular economy concepts applied to the energy storage field.
