There are diverse applications of the technology of microelectromechanical system (MEMS), which were commonly used in vehicle systems in the early stages and had a great progression due to the rapid growth with consuming electronic products and BioMEMS in recent years. The study focuses on the applications of microelectromechanical system, and explores its key technologies and further applications through the patent citation network. The dataset of the study focuses on the technology of MEMS and its applications, searched from Webpat patent database, in a total number of 3325 patents. The differences between cited or citing relationships in the patent citation network will lead to the different search paths. The main path analysis constructs the paths via choosing the most significant search paths, thus the technologies that appear on the main path are usually regarded as the important ones. The main path analysis not only contributes to the understanding of the technology development in the industry but help engineers or researchers to learn the new knowledge quickly. Based on the technologies that the firms have involved in, the study uses cluster analysis separating them into several clusters to find out the role of the clusters with different technology strategies among the development of MEMS technology. The study finds that the mainstreams of MEMS technology are focused on the improvement of the accelerometers in the beginning, which are now spotlight on the micro-actuators. The micro-actuators have advantages such as fast response speed and making larger displacement to the components if needed, and it is usually used in optical and mechanical systems. There are also different kinds of strategies when the firms develop the MEMS technology. In the primary stage, most of the firms put emphasis on the single technique; afterwards, other firms apply MEMS technology in diverse applications.
