Intelligent Poly(vinylidene fluoride)‐Based Materials for Biomedical Applications

Abstract Recent advances in intelligent materials have given rise to a plethora of new wearable and implantable devices in the biomedical fields. As a typical intelligent material, poly(vinylidene fluoride) (PVDF) garners significant attention owing to its eco‐friendliness, excellent biocompatibility, flexibility, processability, and distinctive electroactive properties. Specifically, PVDF exhibits unique piezoelectric and pyroelectric characteristics, making it an ideal candidate for a wide range of applications including innovative physical tweezers, soft robots, sensors, energy harvesting, tissue engineering, and neural stimulation. Despite extensive progress, a comprehensive summary of the fundamentals and biomedical applications of PVDF‐based materials remains largely absent. In this review, we first provide an overview of recent progress in PVDF‐based materials, focusing on the piezoelectric and pyroelectric principles. Additionally, various strategies for enhancing PVDF's piezoelectric and pyroelectric properties and their emerging applications are summarized. Furthermore, the challenges facing PVDF‐based materials in the biomedical field are discussed, offering insights into future prospects for their advancement.
