摘要: 采用陶瓷坯膜流延成型和陶瓷坯膜/金属内电极共烧技术,制作了多层片式高含铅PZT软性压电陶瓷微驱动器.该器件具有体积小、工作电压低、位移量大(38V,1.05μm)的特点.本文对制作的多层片式器件在直流和单向交流工作电压的作用下产生的静态和动态位移特性,从PZT压电陶瓷材料的晶体和电畴结构特点进行了分析和研究.

Abstract: The PZT-based monolithic multilayer piezoelectric actuator (35 layers of piezo-ceramic, one layer 47μm thick) was fabricated by the tape-casting and the ceramic/internal-electrode cofiring method. The actuator shows large displacement under a low voltage (about 1μm displacement under 38V voltage). The static and dynamic displacement characterizations of the PZT-based actuator was discussed on the basis of its lattice structure and domain behaviors.

Key words: tape-casting, PZT-based monolithic multilayer piezoelectric actuator, displacement
