传感器作为信息技术中信息采集、信息传播、信息处理3大领域之一,是不可缺的技术。国外各发达国家都将传感器技术视为现代高技术发展的关键。从80年代起,传感器大国日本就将传感器技术列为发展重点,美国等国家也将此技术列为国家科技和国防技术发展的重点内容。2000年,全球传感器市场约达700亿美元,比1999年增长8.5%;2001年市场总额已达到770亿美元,比2000年增长10%。传感器在我国也获得了一定发展,2000年产量约10亿只,2001年已达11.5亿只,同比增长15%。但与国外和国内客观要求相比,还存在很大差距。我国传感器行业始于五十年代初期,虽起步较早,但直到1986年“七五”开始才正式将传感器技术列入国家重点攻关项目,投入了以机械敏、力敏、气敏、温 As an information technology in the field of information collection, information dissemination, information processing, one of the three major areas, is an indispensable technology. All developed countries in the world regard sensor technology as the key to the development of modern high technology. Since the 1980s, Japan, the sensor power country, has made sensor technology a priority for development. Countries such as the United States have also listed this technology as a key component of national technology and national defense technology development. In 2000, the global sensor market reached about 70 billion U.S. dollars, up 8.5% over 1999; the total market value in 2001 reached 77 billion U.S. dollars, up 10% over 2000. Sensors have also gained some development in our country. In 2000, the output was about 1 billion pieces, reaching 1.15 billion pieces in 2001, an increase of 15% over the same period of last year. However, compared with the objective requirements both at home and abroad, there is still a long way to go. China’s sensor industry began in the early 1950s, although started earlier, it was not until 1986 that the sensor technology was formally included in key national key research projects until 1986, with a focus on mechanical sensing, force sensing, gas sensing, temperature
