Conductive microfibers play a significant role in the flexibility, stretchability, and conductivity of electronic skin (e‐skin). Currently, the fabrication of conductive microfibers suffers from either time‐consuming and complex operations or is limited in complex fabrication environments. Thus, it presents a one‐step method to prepare conductive hydrogel microfibers based on microfluidics for the construction of ultrastretchable e‐skin. The microfibers are achieved with conductive MXene cores and hydrogel shells, which are solidified with the covalent cross‐linking between sodium alginate and calcium chloride, and mechanically enhanced by the complexation reaction of poly(vinyl alcohol) and sodium hydroxide. The microfiber conductivities are tailorable by adjusting the flow rate and concentration of core and shell fluids, which is essential to more practical applications in complex scenarios. More importantly, patterned e‐skin based on conductive hydrogel microfibers can be constructed by combining microfluidics with 3D printing technology. Because of the great advantages in mechanical and electrical performance of the microfibers, the achieved e‐skin shows impressive stretching and sensitivity, which also demonstrate attractive application values in motion monitoring and gesture recognition. These characteristics indicate that the ultrastretchable e‐skin based on conductive hydrogel microfibers has great potential for applications in health monitoring, wearable devices, and smart medicine.

“…Despite the unique advantages of self-healing supramolecular hydrogels in terms of desirable mechanical properties and long-term maintenance of their function, the lack of targeted functionality for biomedical applications still needs to be addressed. Te Ag NPs have been widely used in medical, food, electronic, and other felds because of their high safety, good durability, and no drug resistance [42][43][44][45][46]. With the function of the N-acryloyl glycinamide hydrogel (NH), it was found that the prepared hydrogel demonstrated high tensile strength, large stretchability, and good self-healing.…”

Wound healing due to skin defects is a growing clinical concern. Especially when infection occurs, it not only leads to impair healing of the wound but even leads to the occurrence of death. In this study, a self-healing supramolecular hydrogel with antibacterial abilities was developed for wound healing. The supramolecular hydrogels inherited excellent self-healing and mechanical properties are produced by the polymerization of N-acryloyl glycinamide monomers which carries a lot of amides. In addition, excellent antibacterial properties are obtained by integrating silver nanoparticles (Ag NPs) into the hydrogels. The resultant hydrogel has a demonstrated ability in superior mechanical properties, including stretchability and self-healing. Also, the good biocompatibility and antibacterial ability have been proven in hydrogels. Besides, the prepared hydrogels were employed as wound dressings to treat skin wounds of animals. It was found that the hydrogels could significantly promote wound repair, including relieving inflammation, promoting collagen deposition, and enhancing angiogenesis. Therefore, such self-healing supramolecular hydrogels with composite functional nanomaterials are expected to be used as new wound dressings in the field of healthcare.
