§1概述生物组织的压电性已用木材进行了系统的研究。实践证明,有可能存在压电效应的材料不仅是晶体,各向异性的非晶态的介质亦可能有压电效应,从而发展了压电结构理论。木材的逆压电效应不仅得到证实,并已测定了它的压电常数及其阵列。在取向的羊毛和人类的毛发中观察到了压电性和热电性。发现了当骨头弯曲时有压电极化产生。骨头和腱胶原的正逆压电效应定量试验已完成,由于电流能刺激骨头的生长,使注意力集中到研究骨头及其有关物质的压电性上来。在脱氧核糖核酸(DNA)和蛋白质中发现有压
§1 Overview Piezoelectricity of biological tissues has been studied systematically with wood. Practice has proved that there may be a piezoelectric effect of the material is not only a crystal, anisotropic amorphous medium may have a piezoelectric effect, which developed the piezoelectric structure theory. The inverse piezoelectric effect of wood has not only been confirmed, but its piezoelectric constant and its array have been determined. Piezoelectricity and pyroelectricity were observed in the orientation of wool and human hair. Piezoelectric polarization was found when the bone was bent. Quantification of the positive and negative piezoelectric effects of bone and tendon collagen has been completed and due to the current stimulating bone growth, attention has been focused on the piezoelectricity of bones and their related substances. Pressure is found in DNA and protein
