Piezoelectricity refers to the ability of certain materials to generate electric charges when subjected to mechanical stress or strain, and vice versa. This phenomenon has been widely studied in inorganic materials, such as quartz and ceramics, and has found numerous applications in sensing, actuation, and energy harvesting. There has been a growing interest in piezoelectricity for polymeric materials that are lightweight, flexible, and highly processable for a wide range of applications, including sensors for environmental and biomedical monitoring, energy conversion from mechanical vibrations, and actuation in soft robotics. Note that the characterization of the piezoelectric tendency of polymeric materials tends to be a complex and challenging process, as the effect is often weak and dependent upon various factors including material structure, processing conditions, and measurement setup. While many past and current review articles have covered theories and principles associated with piezoelectric polymers to some extent, detailed information on the corresponding experimental techniques used to measure their piezoelectric properties remains limited. This mini‐review paper aims to consolidate and summarize various approaches, including quasi‐static methods, optical interferometry, dielectric spectroscopy, and piezoelectric force microscopy, and provide insights into the principles, advantages, limitations, and challenges associated with these techniques.This article is protected by copyright.

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.
