面向老年人的传感器技术景观分析与中国对策

The Landscape of Sensor Technology for the Elderly and Chinese Countermeasures

养老科技创新是应对人口老龄化的重要途径和主要支撑,传感器是养老科技创新的重要技术领域。本文运用科学计量分析、社会网络和聚类分析等方法,从成长性与空间分布、专利权人与科技文献作者机构分布、核心专利分布、技术焦点与竞争态势五个方面对涉老传感器技术领域进行全景阐释,揭示涉老传感器技术领域的研究现状,全面展示该领域的竞争格局。研究发现,目前面向老年人的传感器技术领域正处于发展时期,在专利权人排名方面日本企业占据主导地位,而科技文献的作者单位所属国以欧美国家为主,日本与美国分别拥有最多的高被引专利与高价值专利,热点领域主要在电学物理与医疗卫生领域,研究前沿主要集中在智能家居、电子医疗、跌倒风险评估以及步态分析;本文还发现了中国传感器技术创新存在的问题,并为传感器技术创新提供决策建议。

Gerontechnology innovation for the elderly is an important way to deal with the aging of the population and the main support sensor is an important technical field of gerontechnology innovation for the elderly.This paper uses the methods of scientometric analysis,social network and cluster analysis to analyze the field of old sensor technology from five aspects:growth and spatial distribution,distribution of patentees and authors of scientific and technological literature,core patent distribution,technical focus and competitive situation.The research performs a panoramic interpretation to reveal the current research status in the field of old sensor technology,and fully demonstrates the competitive landscape in this field.The study finds out that the sensor technology field for the elderly is currently in a period of development,and Japanese companies dominate the ranking of patentees,while the authors of scientific and technological literature are dominated by European and American countries,and Japan and the United States have the most highly cited patents and high-value patents,the hotspots are mainly in the fields of electrical physics and medical and health,and the research frontiers are mainly focused on smart home,electronic medical,fall risk assessment and gait analysis;This study also reveals problems in Chinese sensor technology innovation,and provides decision-making suggestions for sensor technology innovation.
