中国传感器产业的那些差距

　　清华大学精密仪器系教授董永贵介绍，中国大致从1980年以后开始重视传感器技术的研究。经过多年的努力，在传感器研究方面的发展水平还算是比较好的。但是，在产品化方面的技术进步还不是很理想，很多传感器技术，其实国内的实验室研究水平并不是很差，可惜未能充分利用，没有转化为进入市场的成熟产品。

　　他说，传感器技术的研究需要比较长时间的投入，一款传感器的研发，要6年-8年才能成熟，一般中国企业都承受不了这么长的周期。中国企业更难以承受失败，而传感器的研究失败的风险很高。

　　根据董永贵在日本访问时了解到的情况，日本企业支持的研发中，很多形不成产品，但是企业能够承受，10项中只要2项-3项能够变成产品就行。

　　“相比之下，我们很多企业都是准备去拿别人现有的东西。”董永贵说，这种思路是有问题的，包括我们总是希望引进国外现成的、有自己项目的人才。“都不准备养鱼，而是捞一条鱼来。”

　　相比于比较大型的仪器设备，传感器在产品化过程中需要的投资一般不是很大，所以比较适合小型企业投资。在这方面，中国应该是有优势的。然而，如果从另外一个方面考虑，这也是一个短处。

　　传感器行业的一个特点是，传感器本身技术含量高，但单只传感器的价格一般不高。此特点导致的一个结果是，尽管传感器的技术附加值高，但单纯依赖传感器很难形成可观的产值。

　　按照董永贵教授的比喻，传感器有点像中药里的“药引”，本身功能很重要，但真正形成规模还需要依赖整服药剂才行。国外很多传感器公司一旦在某种传感器上有**，很快会有相关的测量仪器开发出来。

　　而且，在中国的专利保护机制下，传感器中辛辛苦苦研发出来的关键技术，往往呈现一种“诀窍”性质，被抄袭后，很难说清楚，企业也打不起官司。国内虽然也有MEMS传感器企业，但都是委托加工，搞不好就被加工企业自己拿去做了，目前的企业创新体系有很大的问题。

　　2012年的时候，一位国内传感器领域的前辈在一次会议上说，为什么中国传感器事业发展不好，就是缺乏能够到国务院讲课的**人物，这个领域研发的时间长，显着度不够，本身是很小的东西，所依据的物理现象是几十年、上百年前就发现的。

　　这位学者指出，这种研究实际上非常辛苦，比如说有一种加速度传感器，在石油行业中用于地震波测量，所依据的是苏联几十年前提出的原理，但是直到这位专家在苏联解体后，到了美国才形成产品得到应用。

　　“越是需要厚积薄发、广种薄收的领域，我们差距越大。”董永贵认为，现在差距有进一步拉大的趋势。C341BC CUTLER HAMMER
