This study introduces a new conductive hydrogel electronic-skin (e-skin) patch for advanced wound care. The smart e-skin patch accelerates healing, monitors wounds in real-time, and integrates into a wireless system for precision healthcare.
Area of Science:
- Biomaterials Science
- Regenerative Medicine
- Wearable Technology
Background:
- Current hydrogel electronic-skin (e-skin) patches for wound care have limitations including single functionality and inadequate real-time monitoring.
- Existing solutions struggle with adaptability to diverse wound types and effective chronic wound repair.
Purpose of the Study:
- To develop a multifunctional, biomass-derived conductive hydrogel e-skin patch for enhanced wound healing and real-time monitoring.
- To create an integrated wireless system for continuous wound assessment and precision management.
Main Methods:
- Fabrication of the e-skin patch using supramolecular assembly of carboxymethyl cellulose (CMC), carboxymethyl chitosan (CMCS), and poly(vinyl alcohol) (PVA).
- Characterization of the hydrogel's mechanical robustness, conductivity, biocompatibility, antibacterial properties, and photothermal conversion.
- Integration of the e-skin patch sensor with a miniaturized electronic chip for a portable wireless wearable system.
Main Results:
- The e-skin patch demonstrated excellent mechanical properties, conductivity, biocompatibility, and antibacterial performance.
- Achieved a 98% healing rate for full-thickness skin defects within 14 days, with significant inflammation suppression.
- The integrated system enabled real-time monitoring of wound micromovement, temperature, and physiological signals, with data transmission via Bluetooth.
Conclusions:
- The developed multifunctional e-skin patch offers a promising solution for accelerating wound healing and providing intelligent real-time monitoring.
- The integrated wireless system establishes a novel sensing platform for precision wound management and intelligent healthcare applications.
