【正文】 的重大突破，其靈敏度高，僅次于超導(dǎo)量子干涉器件。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。例如用高分子聚合物薄膜制成溫度傳感器；光導(dǎo)纖維 能制成壓力、流量、溫度、位移等多種傳感器；用陶瓷制成壓力傳感器。利用這個(gè)原理制成等離子聚合法聚苯乙烯薄膜溫度傳感器，其有以下特點(diǎn)：測(cè)濕范圍寬；溫度范圍寬，可達(dá) 400℃～ +1500℃；響應(yīng)速度快，小于 1S；尺寸小，可用于小空間測(cè)濕；溫度系數(shù)小。測(cè)量范圍可從 0到60mpa。光纖傳感器與傳統(tǒng)傳感器相比有許多特點(diǎn)：靈敏 度高，結(jié)構(gòu)簡(jiǎn)單、體積小、耐腐蝕、電絕緣性好、光路可彎曲、便于實(shí)現(xiàn)遙測(cè)等。將集成光路器件代替原有 光學(xué)元件和無(wú)源光器件，使光纖傳感器有高的帶寬、低的信號(hào)處理電壓，可靠性高，成本低。核心部分由感壓硅膜片和硅膜片上面制作的兩個(gè)諧振梁結(jié)成，兩個(gè)諧振梁的頻差對(duì)應(yīng)不同的壓力，用頻率差的方法測(cè)壓力，可消除環(huán)境溫度等因素帶來(lái)的誤差。在工業(yè)控制、航空航天領(lǐng)域、生物醫(yī)學(xué)等方面有重要的作用，如飛機(jī)上利用可減輕飛機(jī)重量，減少能源。 智能化傳感器是一種帶微處理器的傳感器，是微型計(jì)算機(jī)和傳感器相結(jié)合的成果，它兼有檢測(cè)、判斷和信息處理功能，與傳統(tǒng)傳感器相比有很多特點(diǎn)： 具有判斷和信息處理功能，能對(duì)測(cè)量值進(jìn)行修正、誤差補(bǔ)償，因而提高測(cè)量精度； 可實(shí)現(xiàn)多傳感器多參數(shù)測(cè)量； 有自診斷和自校準(zhǔn)功能，提高可靠性； 測(cè)量數(shù)據(jù)可存取，使用方便； 有數(shù)據(jù)通信接口，能與微型計(jì)算機(jī)直接通信。美國(guó)宇航局在開(kāi)發(fā)宇宙飛船時(shí)稱(chēng)這種傳感器為靈巧傳感器（ Smart Sensor），在宇宙飛船上這種傳感器是非常重要的。因此，我們應(yīng)該加大對(duì)傳感器技術(shù)研究、開(kāi)發(fā)的投入，使我國(guó)傳感器技術(shù)與外國(guó)差距縮短，促進(jìn)我國(guó)儀器儀表工業(yè)和自化化技術(shù)的發(fā)展。 The temperature range is wide, may reach 400 ℃ ~ +1,500 ℃ 。%/10K, anti overloads strongly, may reach the measuring range several hundred times. The survey scope may from 0 to E+H Corporation and the American Kahlo Corporation product is at the leading position. The optical fiber application is send the material significant breakthrough, its uses in most early the optical munication techniques. In the optical munication use discovered works as environmental condition change and so on the temperature, pressure, electric field, magic field, causes the fiber optic transmission light wave intensity, the phase, the frequency, change and so on the polarization condition, the survey light wave quantity change, may know causes these light wave physical quantity the and so on quantitative change temperature, pressure ,electric field, magic field size, uses these principles to be possible to develop the optical fiber sensor. The optical fiber sensor and the traditional sensor pare has many characteristics: Sensitivity high, the structure simple, the volume small, anti corrosive, the electric insulation good, the path of rays may be curving, be advantageous for the realization telemeter and so on. Optical fiber sensor Japan is in the advanced level. Like Idec Izumi Corporation and Sun x Corporation. The optical fiber send receiver and the integrated path of rays technology unify, accelerates the optical fiber sensor technology development. Will integrate the path of ray’s ponent to replace the original optics part and the passive light ponent。 May realize the multisensor multi parameters survey。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.
