“…However, G ′ and G ″ could immediately recover their initial values as the strain returned to 1% (within 15 s), due to the rapid reconstruction of the hydrogel network. The moduli ( G ′ and G ″) of the P(AA‐ co ‐LMA)‐Zr 4+ hydrogels barely changed after 5 cycles of structural destruction and reconstruction, confirming excellent self‐healing capability 40,41 …”

Responsive hydrogels hold great promise for applications such as biological tissue engineering, controlled drug release, soft actuators, and intelligent sensors. However, the design and construction of robust responsive hydrogels using a simple method remains a significant challenge. Herein, a non‐covalently crosslinked responsive hydrogel was constructed by introducing carboxyl‐Zr4+ metal coordination to the hydrophobic association network of P(AA‐co‐LMA) hydrogel through a facile one‐pot polymerization method. The incorporation of multiple reversible interactions, including hydrogen bonding, metal coordination, and hydrophobic association, resulted in a responsive hydrogel with exceptional mechanical strength (≈2.92 MPa), outstanding flexibility (elongation>1000%), and rapid response to pH alterations. Furthermore, the hydrogel also presented good ionic conductivity due to the abundant movable ions, as well as high sensitivity and stability. As application demonstrations, the supermolecular hydrogel had been successfully used in actuating and strain sensing. This work establishes an effective design strategy for creating tough and multifunctional responsive hydrogel.

“…In order to reduce the aggregation of carbon nanotubes, tannic acid (TA)-modified carbon nanotubes (TA-CNTs) could be prepared on the surface of carbon nanotubes (MWCNTs), which could effectively increase the dispersion of carbon nanotubes in hydrogels. 82 For example, He et al 83 prepared conductive hydrogels by doping TA-CNTs into the polyvinyl alcohol (PVA) matrix containing a water-glycerol dispersion medium (Fig. 3a).…”

Conductive hydrogels (CHs) have received significant attention for use in wearable devices because they retain their softness and flexibility while maintaining high conductivity. CHs are well suited for applications in skin‐contact electronics and biomedical devices owing to their high biocompatibility and conformality. Although highly conductive hydrogels for smart wearable devices are extensively researched, a detailed summary of the outstanding results of CHs is required for a comprehensive understanding. In this review, the recent progress in the preparation and fabrication of CHs is summarized for smart wearable devices. Improvements in the mechanical, electrical, and functional properties of high‐performance wearable devices are also discussed. Furthermore, recent examples of innovative and highly functional devices based on CHs that can be seamlessly integrated into daily lives are reviewed.
