Flexible sensors have attracted great research interest due to their applications in artificial intelligence, wearable electronics, and personal health management. However, the inherent brittleness of common hydrogels, preparing a hydrogel-based sensor integrated with excellent flexibility, self-recovery, antifatigue properties still remains challenge date. In this study, type physically chemically dual-cross-linked conductive hydrogels based on 2,2,6,6-tetramethylpiperidine-1-oxyl...
Abstract The human skin, an important sensory organ, responds sensitively to external stimuli under various harsh conditions. However, the simultaneous achievement of mechanical/thermal sensitivity and extreme environmental tolerance remains enormous challenge for skin‐like hydrogel‐based sensors. In this study, a novel skin‐inspired hydrogel–elastomer hybrid with sandwich structure strong interfacial bonding mechanical–thermal multimode sensing applications is developed. An inner‐layered...
Flexible electroluminescent (EL) devices have become an important part of lighting and display. However, fabricating a flexible EL device with biodegradability, recyclability, extreme environment tolerance through facile green method still remains challenging to date. Herein, all-nanocellulose-based recyclable phosphors is developed by using sandwich-structured assembly strategy. Biomass-derived cellulose nanocrystals II crystalline allomorphs (CNCs II) high transmittance are utilized as...
Recently, with the development of personal wearable electronic devices, demand for portable power is miniaturization and flexibility. Electro-conductive hydrogels (ECHs) are considered to have great application prospects in energy-storage devices. However, synergistic properties self-healability, viscoelasticity, ideal electrochemistry key problems.

With the rapid development of soft electronics, flexible and stretchable strain sensors are highly desirable. However, coupling high sensitivity stretchability in a single sensor remains challenge. Herein, kind conductive elastomer is constructed with poly(dimethylsiloxane) (PDMS) silylated cellulose nanocrystal (SCNC)/carbon nanotube (CNT) nanohybrids through facile one-pot solution-casting method. The hydrophobic SCNCs can effectively facilitate dispersion CNTs PDMS synergistically improve...
