Abstract
Bacterial infections of the wound surface can be painful for patients, and traditional dressings do not effectively address this problem. In this study, an antimicrobial wound dressing is prepared using a novel antimicrobial peptide, HX-12C. This hydrogel system is based on the natural biomaterials sodium alginate and gelatin, utilizing calcium carbonate as a source of Ca2+ , and ionic cross-linking is facilitated by lowering the solution pH. The resulting sodium alginate/gelatin HX-12C-loaded hydrogel (CaAGEAM) has good mechanical and adhesion properties, biocompatibility and in vitro degradability. Its extraordinary antibacterial efficacy (>98%) is verified by an antibacterial experiment. More importantly, in vivo experiments further demonstrate its healing-promotion effect, with a 95% wound healing rate by day 9. Tissue staining demonstrates that the hydrogel containing antimicrobial peptides is effective in suppressing inflammation. The dressing promotes wound healing by stimulating the deposition of skin appendages and collagen. The results of this study suggest that composite hydrogels containing antimicrobial peptides are a promising new type of dressing to promote the healing of infected wounds.

Abstract
Polymer-based conductive hydrogels have the synergistic advantages of high conductivity and tissue-like properties, making them promising candidates for the construction of flexible electronic devices. However, conductive hydrogel materials can easily absorb microorganisms due to their high water content. To address the problem that conductive hydrogels are susceptible to infection by external pathogens when monitoring wounds and when used in implanted organs, tannic acid-borax (TA-B) complexes are introduced into classical dual network polyacrylamide/agarose (PAM/Agar) hydrogels to form PAM/Agar/TA-B hydrogel conductors. These hydrogels are antibacterial and have good mechanical properties, light transmission, electrical conductivity, and adhesion. TA-B increases the compressive stress of the PAM/Agar/TA-B hydrogel by 58.14% compared to a PAM/Agar hydrogel. The PAM/Agar/TA-B hydrogel can be used as an electronic conductor for electronic skin and wearable sensors. Outstanding biocompatibility allows the hydrogel to be used as a monitoring device at wounds to monitor heartbeat, skin wounds, and internal tissue status in real time. In summary, an antibacterial strain sensing matrix that is safe for human health monitoring is developed.
