Electric-based dressing for wound management

Abstract

Electrical stimulation directs cell behavior via spatially controlled electric fields to enhance tissue regeneration and wound healing. Electrets, a class of functional materials with permanent polarization, offer distinct advantages, such as low cost, stable and sustained electric field output, and excellent biocompatibility, positioning them as promising candidates for therapeutic applications. This minireview summarizes the main recent progress in organic electret-based materials for wound management, including an introduction to wound treatment and advances in electret-based therapy for accelerated wound healing, infection control, and wound monitoring. Finally, the key challenges and future directions for clinical translation and theoretical development are discussed.

Keywords: electret; electrical stimulation; hypertrophic scar; infection; wound healing.
