【導(dǎo)讀】傳感器是一種能將物理量、化學(xué)量、生物量等轉(zhuǎn)換成電信號(hào)的器件。正確感受被測(cè)量并轉(zhuǎn)換成相應(yīng)輸出量，對(duì)系統(tǒng)的質(zhì)量起決定性作用。求越來(lái)越高，還要求其成本低廉且使用方便。性、體積、成本等已難以滿足而逐漸被淘汰。對(duì)傳感器新技術(shù)的研究與開(kāi)發(fā)，并且都已取得極大的突破。日本夏普公司利用超導(dǎo)技術(shù)研制成功高溫超導(dǎo)磁性傳感器，是傳。感器技術(shù)的重大突破，其靈敏度高，僅次于超導(dǎo)量子干涉器件。工藝遠(yuǎn)比超導(dǎo)量子干涉器件簡(jiǎn)單。利用抗體和抗原在電極表面上相遇復(fù)合時(shí)，會(huì)引起電極電位的變化，利用這一現(xiàn)象可制出免疫傳感器。用這種抗體制成的免疫傳感器可對(duì)某生。物體內(nèi)是否有這種抗原作檢查。如用肝炎病毒抗體可檢查某人是否患有肝。炎，起到快速、準(zhǔn)確作用。光纖傳感器與傳統(tǒng)傳感器相比有。將集成光路器件代替原有光學(xué)元件和無(wú)源光器件，使光。具有校準(zhǔn)、補(bǔ)償、自診斷和網(wǎng)絡(luò)通信的功能，它可降低成本、增加產(chǎn)量，代以來(lái)，傳感器技術(shù)向更新、更高的技術(shù)發(fā)展。
【正文】 ig, shorting and so on slow change, had the precision high, the reliability is high, the volume small characteristic, widely used in domain and so on aviation, petroleum, chemical industry, medical service. Integrates the sensor the superiority is the traditional sensor is unable to achieve, it is a simple sensor not merely, it in at the same time the auxiliary circuit part and send the part will integrate on together the chip, will cause it to have the calibration, to pensate, from the diagnosis and the work correspondence function, it might reduce the cost, the gain in yield, this kind of blood pressure sensor which American LUCAS, NOVASENSOR Corporation will develop, each week will be able to produce 10,000. The intellectualized sensor is one kind of belt microprocessor sensor, is achievement which the microputer and the sensor unifies, it has at the same time the examination, the judgment and the information processing function, pares with the traditional sensor has very many characteristics: Has the judgment and the information processing function, can carry on the revision, the error to the observed value pensates, thus enhancement measuring accuracy。 May realize the multisensor multi parameters survey。 Has from the diagnosis and from the calibration function, enhances the reliability。 The survey data may deposit and withdraw, easy to operate。 Has the data munication interface, can and the microputer direct munication. The sensor, the signal adjustment electric circuit, the monolithic integrated circuit integration forms ultra largescale integrated on a chip the senior intelligence sensor. American HONY WELL Corporation ST3000 intelligence sensor, the chip size only then has 342mm3, uses the semiconductor craft, makes CPU, EPROM, the static pressure, the differenti al pressure, the temperature on the identical chip and so on three kind of sensitive units. The intellectualized sensor research and the development, US is at the leading position. American Space Agency when development spaceship called this kind of sensor for the clever sensor (Smart Sensor), on the spaceship this kind of sensor is extremely important. Our country in this aspect research and development also very backward mainly is because our country semiconductor integrated circuit technological level is limited. The sensor’s development is changing day after day since especially the 8039。s humanities have entered into the high industrialization the information age, sensor technology to renewal, higher technological development. US, Japan and so on developed country sensor technological development quickest, our country because the foundation is weak, the sensor technology pares with these developed countries has the big disparity. Therefore, we should enlarge to the sensor engineering research, the development investment, causes our country sensor technology and the foreign disparity reduces, promotes our country instrument measuring appliance industry and from the technical development.
