Biomaterials-enabled electrical stimulation for tissue healing and regeneration.

The electrical microenvironment is considered a pivotal determinant in various pathophysiological processes, including tissue homeostasis and wound healing. Consequently, extensive research endeavors have been directed toward applying electricity to cells and tissues through external force devices or biomaterial-based platforms. In addition to in situ electroconductive matrices, a new class of electroactive biomaterials responsive to stimuli has emerged as a focal point of interest. These electroactive materials, in response to intrinsic biochemical (e.g., glucose) or external physical stimuli (e.g., light, magnetism, stress), hold significant potential for cell stimulation and tissue regeneration. In this communication, we underscore this distinct category of electroactive biomaterials, discussing the currently developed biomaterial platforms and their biological roles in stimulating cells and tissues during the healing and regeneration process. We also critically evaluate the inherent limitations and challenges of these biomaterials while offering forward-looking insights into their promise for future clinical translations.
