Micro-power generation device referring in this paper is to operate organization by hands or feet, so as to cut the lines of magnetic force or change the coil magnetic flux to generate electricity. This device can change me-chanical kinetic energy into electrical energy. Its power in milliwatts can provide electricity for electronic products. Electronic products are able to be as a power source without battery, so as to avoid a series of problems of using the battery. This device has the advantages of strong reliability, lower cost, and friendly environment. This paper ana-lyzes the structure of the apparatus, the power generation principle, the selection principle, and the analysis of the ap-plication. In this paper, the application of analysis is only for intelligent electrical field. The micro-power generation technology is popular in the market due to its characteristics of environmental protection and energy-saving. Further-more, this paper will detail how to apply it and its specific application characteristics.%本文所指微发电装置是指通过手或脚来操作一个机构，从而切割磁力线或改变线圈磁通量发电，将机械动能转化为电能的一个装置，其发电功率在毫瓦级，其所发电可以为电子产品供电，电子产品则可以不需要采用电池作为电源，避免使用电池存在的一系列问题。该装置使用可靠性较强，节约用户成本，且使用环保。本文分析该装置的结构组成、发电原理、选材原则以及应用分析。本文应用分析仅限于智能电工领域，因该微发电技术具有环保，节能特点而受到市场热捧，如何应用以及他的具体应用特点，本文将详细叙述。
