Bioelectricity provides electrostimulation to regulate cell/tissue behaviors and functions. In the human body, bioelectricity can be generated in electromechanically responsive tissues and organs, as well as biomolecular building blocks that exhibit piezoelectricity, with a phenomenon known as the piezoelectric effect. Inspired by natural bio‐piezoelectric phenomenon, efforts have been devoted to exploiting high‐performance synthetic piezoelectric biomaterials, including molecular materials, polymeric materials, ceramic materials, and composite materials. Notably, piezoelectric biomaterials polarize under mechanical strain and generate electrical potentials, which can be used to fabricate electronic devices. Herein, we propose a review article to summarize the design and research progress of piezoelectric biomaterials and devices toward bionanotechnology. We first introduce the functions of bioelectricity in regulating human electrophysiological activity from cellular to tissue level. Next, recent advances as well as structure‐property relationship of various natural and synthetic piezoelectric biomaterials are provided in detail. In the following part, we systematically classify and discuss the applications of piezoelectric biomaterials in tissue engineering, drug delivery, biosensing, energy harvesting, and catalysis. Finally, the challenges and future prospects of piezoelectric biomaterials are presented. We believe that this review will provide inspiration for the design and development of innovative piezoelectric biomaterials in the fields of biomedicine and nanotechnology.This article is protected by copyright.

Piezoelectric composites have received widespread attentions in the fields of biomedicine and in vitro wearable devices due to their ability to convert mechanical forces into charge signals. The preparation of piezoelectric composites with complex structures through 3D printing technology can not only effectively improve their piezoelectric output, but also enable their customized therapeutic applications. This paper first introduces the types of piezoelectric composites and reviews the 3D printing technology commonly used in their preparation, analyzing the advantages and disadvantages of each 3D printing technology. Then, the state‐of‐the‐art of the biomedical applications of piezoelectric composites, including drug sustained‐release, wound healing promotion, bone tissue cells growth promoting, neurorehabilitation stimulating, ultrasonic diagnosis, and in vivo biosensing and in vitro wearable sensing, are emphasized. Finally, the main factors affecting the applications of 3D printed piezoelectric composites are outlooked, and an in‐depth discussion on the challenges toward 3D printed piezoelectric composites are analyzed. This review is believed to provide some fundamental knowledge of 3D printed piezoelectric composites.
