摘　　要：喷墨头是喷墨数字印刷系统的核心部件,其工作原理和结构决定了工作的可靠性和制造成本。阐述了压电式喷墨头的工作原理,分析了一种典型的压电式喷墨头的结构与特点,并介绍了压电式喷墨头的MEMS制造技术,综述了压电式喷墨头的发展现状,指出压电式喷墨头技术被国外垄断,喷墨头实现国产化是专业研究人员的重要任务。The inkjet printhead is the core componentof inkjet digital printing system, its working principle and structure determine the working reliability and manufacturing cost. This paper illustrated the working principle of piezoelectric inkjet printhead, analyzed akind of typical piezoelectric inkjet printhead structure andthe characteristics of piezoelectric inkjet printhead,and introduced the MEMS manufacturing technology of piezoelectric inkjet printhead, and summarized the devolepment situation of piezoelectric inkjet printhead, pointed out the defects of piezoelectric inkjet technology by foreign monopoly. In order to realize the localization, it becomes an important task of professional researchers.
