Abstract Ionic conductive hydrogels (ICHs) integrate the performance and soft nature of tissue‐like materials to imitate features human skin with mechanical sensory traits; thus, they are considered promising substitutes for conventional rigid metallic conductors when fabricating human‐motion sensors. However, simultaneous incorporation excellent stretchability, toughness, ionic conductivity, self‐healing, adhesion via a simple method remains grand challenge. Herein, novel ICH platform is proposed by designing phenylboronic acid‐ionic liquid (PBA‐IL) multiple roles that simultaneously realize highly mechanical, electrical, versatile properties. This elaborately designed semi‐interpenetrating network fabricated facile one‐step approach introducing cellulose nanofibrils (CNFs) into PBA‐IL/acrylamide cross‐linked network. Ingeniously, dynamic boronic ester bonds physical interactions (hydrogen electrostatic interactions) endow these remarkable stretchability (1810 ± 38%), toughness (2.65 0.03 MJ m −3 ), self‐healing property (92 2% efficiency), adhesiveness, transparency. Moreover, construction this material shows CNFs can synergistically enhance conductivity. The wide working strain range (≈1000%) high sensitivity (GF = 8.36) make candidate constructing next generation gel‐based sensor platforms.

Abstract Over the past decade, conductive hydrogels have received great attention as tissue-interfacing electrodes due to their soft and tissue-like mechanical properties. However, a trade-off between robust properties good electrical has prevented fabrication of tough, highly hydrogel limited its use in bioelectronics. Here, we report synthetic method for realization mechanically tough with modulus. We employed template-directed assembly method, enabling arrangement disorder-free, highly-conductive nanofibrous network inside stretchable, hydrated network. The resultant exhibits ideal material. Furthermore, it can provide adhesion (800 J/m 2 ) diverse dynamic wet tissue after chemical activation. This enables suture-free adhesive-free, high-performance successfully demonstrated ultra-low voltage neuromodulation high-quality epicardial electrocardiogram (ECG) signal recording based on vivo animal models. provides platform interfaces various bioelectronic applications.

Hydrogels have been attracting increasing attention for application in wearable electronics, due to their intrinsic biomimetic features, highly tunable chemical-physical properties (mechanical, electrical, etc.), and excellent biocompatibility. Among many proposed varieties of hydrogels, conductive polymer-based hydrogels (CPHs) emerged as a promising candidate future sensor designs, with capability realizing desired features using different tuning strategies ranging from molecular design (with low length scale 10-10 m) micro-structural configuration (up 10-2 m). However, considerable challenges remain be overcome, such the limited strain sensing range mechanical strength, signal loss/instability caused by swelling/deswelling, significant hysteresis signals, de-hydration induced malfunctions, surface/interfacial failure during manufacturing/processing. This review aims offer targeted scan recent advancements CPH based technology, establishment dedicated structure-property relationships lab advanced manufacturing routes potential scale-up production. The CPHs sensors is also explored, suggested new research avenues prospects included.
