某些材料在受力时其表面会产生电荷,反之,对它加电压时该材料又具有伸缩性。这样的材料一般称为压电材料,典型的有早已被人们熟知的水晶、罗谢尔盐和广泛实用的钛酸钡、钛锆酸铅(PZT)陶瓷。 除了上述无机材料之外,还研究有机材料,大约在1983年就已研制成功采用有 Some materials in the force when the surface will have a charge, on the contrary, the voltage applied to it when the material has flexibility. Such materials are commonly referred to as piezoelectric materials and typically have been well known crystal, Rochelle salts and widely available barium titanate, lead zirconate titanate (PZT) ceramics. In addition to the above-mentioned inorganic materials, organic materials have also been studied and have been successfully developed in about 1983
