Abstract

Experimental evidence shows that natural bone is piezoelectric, and bioelectric phenomena in natural bone play an essential role in bone development and bone defect repair. Piezoelectric ceramics can deform with physiological movements and consequently deliver electrical stimulation to cells or damaged tissue without the need for an external power source. They exhibit piezoelectricity and good biological properties similar to those of natural bone and have shown great potential in bone tissue engineering. This study aims to present an overview of the relationship between electrical stimulation and bone repair as well as the principle of the piezoelectric effect, emphasizing the material characteristics, research progress and application of piezoelectric ceramics in bone tissue regeneration. The limitations of piezoelectric ceramics in promoting osteogenesis by electrical stimulation were also analysed. Overall, this review comprehensively emphasized the essential characteristics of piezoelectric ceramics and pointed out the new direction for the future development of piezoelectric ceramics.

无铅压电陶瓷——一种电活性材料，为骨骼再生提供电刺激线索

实验证明，天然骨具有压电性，天然骨中的生物电现象在骨发育和骨缺损修复中起着重要作用。压电陶瓷可以随着生理运动而变形，从而在不需要外部电源的情况下向细胞或受损组织提供电刺激。它们具有与天然骨相似的压电性和良好的生物学特性，在骨组织工程中具有很大的应用潜力。本研究旨在综述电刺激与骨修复的关系以及压电效应的原理，重点介绍压电陶瓷的材料特性、研究进展及其在骨组织再生中的应用。分析了压电陶瓷在电刺激下促进骨生成的局限性。总的来说，本文全面强调了压电陶瓷的本质特性，并指出了压电陶瓷未来发展的新方向。
