Abstract

This study analyzed the generation rule of streaming potential (SP) considering the piezoelectric effect of bone under static and dynamic compression. The piezoelectric equation was introduced into the equation of SP, and an osteon's 3D fluid-structure interaction finite element model with osteocytes was developed using COMSOL software. Seven working conditions helped study SP. The results showed positive and negative SP alternately acted on osteocyte under dynamic loads, and SP was about three orders of magnitude higher than that under static loads. Therefore, dynamic loads improved the osteocytes' force-electric microenvironment. The force-electric effect revealed the mechanism of treatment of osteoporosis.

静态和动态压缩下压电骨和骨细胞的力电效应的仿真研究。

本文分析了考虑骨在静、动态压缩下的压电效应的流动电位（SP）的产生规律。在SP方程中引入压电方程，利用COMSOL软件建立骨细胞与骨细胞的三维流固耦合有限元模型。7种工况有助于对SP的研究。结果显示，动态负荷下，SP阳性与阴性交替作用于骨细胞，且SP比静态负荷下的作用高约3个数量级。因此，动态载荷改善了骨细胞的力电微环境。力电效应揭示了骨质疏松症的治疗机制。
