全球MEMS传感器技术创新现状与趋势——基于2000-2014年专利分析

Analysis of Development and Innovation Trend of MEMS Sensor Based on Patent from 2000 to 2014

摘要:

以MEMS传感器为主要研究对象,基于德温特专利数据库中收录的优先权年为2000-2014年的MEMS传感器相关专利数据,以发展速度不同划分为三个阶段,分别讨论了各阶段传感器类型、IPC分布以及专利权人分布的变化情况。结果表明MEMS传感器为市场导向型技术,不同阶段的研究重点与该阶段的市场需求有着紧密的联系,我国MEMS传感器在技术创新的同时应加快产业化的步伐。

Abstract:

In this paper, the main research object was MEMS sensor, the patents data was collected from Derwent Innovation Index (DII), first an analysis of patent distribution in the year between 2000 to 2014 was done, and obtained three development stages, then the MEMS sensor type, IPC distribution as well as the major research institutions in different stage was analyzed. Results showed that the development of MEMS sensor was closed contact with market demand, the technological innovation and industrial development of MEMS sensor should carry out at the same time in China.
