44、器能正確感受被測(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。自動(dòng)化程度越高,系統(tǒng)對(duì)傳感器要求越高。在今天的信息時(shí)代里,信息產(chǎn)業(yè)包括信息采集、傳輸、處理三部分,即傳感技術(shù)、通信技術(shù)、計(jì)算機(jī)技術(shù)?,F(xiàn)代的計(jì)算機(jī)技術(shù)和通信技術(shù)由于超大規(guī)模集成電路的飛速發(fā)展,而已經(jīng)充分發(fā)達(dá)后,不僅對(duì)傳感器的精度、可靠性、響應(yīng)速度、獲取的信息量要求越來(lái)越高,還要求其成本低廉且使用方便。顯然傳統(tǒng)傳感器因功能、特性、體積、成本等已難以滿足而逐漸被淘汰。世界許多發(fā)達(dá)國(guó)家都在加快對(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。如今傳感器新技術(shù)的發(fā)展,主要有以下幾個(gè)方面:一、 發(fā)現(xiàn)并利用新現(xiàn)象利用物理現(xiàn)象、化學(xué)反應(yīng)、生物效

45、應(yīng)作為傳感器原理,所以研究發(fā)現(xiàn)新現(xiàn)象與新效應(yīng)是傳感器技術(shù)發(fā)展的重要工作,是研究開(kāi)發(fā)新型傳感器的基礎(chǔ)。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。它的制造工藝遠(yuǎn)比超導(dǎo)量子干涉器件簡(jiǎn)單。可用于磁成像技術(shù),有廣泛推廣價(jià)值。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。美國(guó)加州大學(xué)巳研制出這類傳感器。二、利用新材料傳感器材料是傳感器技術(shù)的重要基礎(chǔ),由于材料科學(xué)進(jìn)步,人們可

46、制造出各種新型傳感器。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。高分子聚合物能隨周?chē)h(huán)境的相對(duì)濕度大小成比例地吸附和釋放水分子。高分子電介常數(shù)小,水分子能提高聚合物的介電常數(shù)。將高分子電介質(zhì)做成電容器,測(cè)定電容容量的變化,即可得出相對(duì)濕度。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。陶瓷電容式壓力傳感器是一種無(wú)中介液的干式壓力傳感器。采用先進(jìn)的陶瓷技術(shù),厚膜電子技術(shù),其技術(shù)性能穩(wěn)定,年漂移量小于0.

47、1%f.s,溫漂小于 0.15%/10k,抗過(guò)載強(qiáng),可達(dá)量程的數(shù)百倍。測(cè)量范圍可從0到60mpa。德國(guó)e+h公司和美國(guó)kavlio公司產(chǎn)品處于領(lǐng)先地位。光導(dǎo)纖維的應(yīng)用是傳感材料的重大突破,其最早用于光通信技術(shù)。在光通信利用中發(fā)現(xiàn)當(dāng)溫度、壓力、電場(chǎng)、磁場(chǎng)等環(huán)境條件變化時(shí),引起光纖傳輸?shù)墓獠◤?qiáng)度、相位、頻率、偏振態(tài)等變化,測(cè)量光波量的變化,就可知道導(dǎo)致這些光波量變化的溫度、壓力、電場(chǎng)、磁場(chǎng)等物理量的大小,利用這些原理可研制出光導(dǎo)纖維傳感器。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。光纖傳感器日本處于先進(jìn)水平。如 idecizumi公司和sunx公司。光纖傳感受
