Ionic conductive eutectogels have great application prospects in wearable strain sensors owing to their temperature tolerance, simplicity, and low cost. Eutectogels prepared by cross-linking polymers good tensile properties, strong self-healing capacities, excellent surface-adaptive adhesion. Herein, we emphasize for the first time potential of zwitterionic deep eutectic solvents (DESs), which betaine is a hydrogen bond acceptor. Polymeric were directly polymerizing acrylamide DESs. The obtained owned ionic conductivity (0.23 mS cm-1), superior stretchability (approximately 1400% elongation), (82.01%), self-adhesion, wide tolerance. Accordingly, eutectogel was successfully applied self-adhesive sensors, can adhere skins monitor body motions with high sensitivity cyclic stability over range (-80 80 °C). Moreover, this sensor an appealing sensing function on bidirectional monitoring. findings work pave way design soft materials versatility environmental adaptation.

Ionic gels from eutectic mixtures are attracting extensive interest in bioelectronics owing to their nonvolatile nature, low cost, and inherently high ionic conductivity. Biodegradable electronics made of biopolymers envisage a promising future this field, but unfortunately, they often feature poor mechanics. Herein, we explored tannic acid-decorated cellulose nanocrystals (TA@CNC) as dynamic nanofillers biocompatible eutectogels based on gelatin mixture composed choline chloride ethylene glycol (ethaline). Small concentrations TA@CNC (up 1–2 wt %) allow increasing by two-fold the strength (30 kPa) stretchability (180%) while improving conductivity (105 mS·m–1). The reversible physical network protein multiple hydrogen bonding interactions with acid endow these good self-adhesiveness, suitable gel-to-sol transition for 3D printing, recyclability. We further used nanocomposite skin-conformal electrodes monitoring different motions human body excellent sensitivity open air thanks volatility ethaline. All all, results demonstrate facile strategy boost properties biopolymer using inexpensive renewable raw materials rigid nanoreinforcers.

The development of degradable, cost-effective, and eco-friendly ionic conductive gels is highly required to reduce electronic waste originating from flexible devices. However, biocompatible, tough, durable are challenging achieve. Herein, we develop a facile strategy for the design synthesis degradable tough eutectogels by integrating an electrostatically driven supramolecular network composed branched polyacrylic acid (PAA) monoethanolamine (MEA) into green deep eutectic solvent with chitosan quaternary ammonium salt (CQS). specially designed PAA/MEA/CQS present multiple desired properties, including high transparency, widely adjustable mechanical resilience, reliable adhesiveness, excellent self-healing ability, good conductivity, remarkable anti-freezing performance, antibacterial properties. dynamic reversible interactions not only significantly enhance properties but also enable fast degradation, addressing dilemma between strength degradability. More importantly, biocompatible multifunctional skin successfully fabricated based on eutectogel, exhibiting sensitivity, wide sensing range, rapid response speed toward strain, pressure, temperature. Thus, this study offers promising fabricating eutectogels, which show great potential as high-performance skins next-generation wearable
