Abstract

The skin, as the body's largest organ, plays a crucial role in protecting against mechanical forces and infections, maintaining fluid balance, and regulating body temperature. Therefore, skin wounds can significantly threaten human health and cause a heavy economic burden on society. Recently, bioelectric fields and electrical stimulation (ES) have been recognized as a promising pathway for modulating tissue engineering and regeneration of wounded skin. However, conventional hydrogel dressing lacks electrical generation capabilities and usually requires external stimuli to initiate the cell regeneration process, and the role of ES in different stages of healing is not fully understood. Therefore, to endow hydrogel-based wound dressings with piezoelectric properties, which can accelerate wound healing and potentially suppress infection via introducing ES, piezoelectric hydrogels (PHs) have emerged recently, combining the advantages of both piezoelectric nanomaterials and hydrogels beneficial for wound healing. Given the scarcity of systematic literature on the application of PHs in wound healing, this paper systematically discusses the principles of the piezoelectric effects, the design and fabrication of PHs, their piezoelectric properties, the way PHs trigger ES and the mechanisms by which they promote wound healing. Additionally, it summarizes the recent applications of PHs in various types of wounds, including traumatic wounds, pressure injuries, diabetic wounds, and infected wounds. Finally, the paper proposes future directions and challenges for the development of PH wound dressings for wound healing.
