摘要
阐述了一种基于微机电系统的纳米力学测量方法和系统。开发了一种多功能的纳牛力致动器,可同时满足微拉伸测试系统、原子力显微镜等系统的需要,该致动器基于微机电系统,以静电侧向梳齿为基本结构,采用变间隙设计结构,实现小芯片尺寸、低压驱动、高分辨率(nN量级)和大输出力(大于1mN),并介绍了该测试系统的原理、结构、微机电系统的安装以及一些相关实验结果。
The development and test of nanomechanical measurement methods and systems on the basis of Micro Electromechanical Systems(MEMS) is described. A MEMS-based nanoforce actuator is presented, which is developed on the basis of an electrostatic lateral comb-drive, mainly for use in material miero/nano tensile testing and atom force microscope. In order to increase the output force, a post-fabrication gap reduction method is introduced, so that the nanoforee actuator shows such features as small size, low drive voltage, high resolution ( in the order of nN) and large actuation force ( 〉1 mN), etc. Then the principle of these measurement systems, the design, the manufacture and the assembly of the MEMS as well as first test results and achieved performance parameters are described.
