Abstract
The piezoelectric effect of wood is explained using practical examples. The mechanisms of piezoelectricity in wood, cellulose, and cellulose derivatives are analyzed based on observations of the relationship between piezoelectric temperature and dielectric and elastic properties. The piezoelectric temperature dispersions characteristics are different in various wood species. Liquid ammonia treatment, delignification treatment, and noncrystalline treatment causes variations in the piezoelectric behaviors. The relationship between the crystallinity and the components of wood chemical structure is analyzed using the two-phase model. The cellulose derivatives are explained in the outline about a highly utilization.
Finally, some recommendations are made, such as the development of device, the development of a nondestruction evaluation method, and the clarification of the piezoelectric behavior in a living tree.
