在現(xiàn)代工業(yè)生產(chǎn)尤其是自動(dòng)化生產(chǎn)過(guò)程中，要用各種傳感器來(lái)監(jiān)視和控制生產(chǎn)過(guò)程中的各個(gè)參數(shù)，使設(shè)備工作在正常狀態(tài)或比較好狀態(tài)，并使產(chǎn)品達(dá)到比較好的質(zhì)量。因此可以說(shuō)，沒(méi)有眾多的優(yōu)良的傳感器，現(xiàn)代化生產(chǎn)也就失去了基礎(chǔ)。在基礎(chǔ)學(xué)科研究中，傳感器更具有突出的地位?，F(xiàn)代科學(xué)技術(shù)的發(fā)展，進(jìn)入了許多新領(lǐng)域：例如在宏觀上要觀察上千光年的茫茫宇宙，微觀上要觀察小到fm的粒子世界，縱向上要觀察長(zhǎng)達(dá)數(shù)十萬(wàn)年的天體演化，短到s的瞬間反應(yīng)。此外，還出現(xiàn)了對(duì)深化物質(zhì)認(rèn)識(shí)、開拓新能源、新材料等具有重要作用的各種極端技術(shù)研究，如超高溫、**溫、超高壓、超高真空、***磁場(chǎng)、超弱磁場(chǎng)等等。顯然，要獲取大量人類感官無(wú)法直接獲取的信息，沒(méi)有相適應(yīng)的傳感器是不可能的。許多基礎(chǔ)科學(xué)研究的障礙，首先就在于對(duì)象信息的獲取存在困難，而一些新機(jī)理和高靈敏度的檢測(cè)傳感器的出現(xiàn)，往往會(huì)導(dǎo)致該領(lǐng)域內(nèi)的突破。一些傳感器的發(fā)展，往往是一些邊緣學(xué)科開發(fā)的先驅(qū)。

壓阻式壓阻式傳感器是根據(jù)半導(dǎo)體材料的壓阻效應(yīng)在半導(dǎo)體材料的基片上經(jīng)擴(kuò)散電阻而制成的器件。其基片可直接作為測(cè)量傳感元件，擴(kuò)散電阻在基片內(nèi)接成電橋形式。當(dāng)基片受到外力作用而產(chǎn)生形變時(shí)，各電阻值將發(fā)生變化，電橋就會(huì)產(chǎn)生相應(yīng)的不平衡輸出。用作壓阻式傳感器的基片（或稱膜片）材料主要為硅片和鍺片，硅片為敏感材料而制成的硅壓阻傳感器越來(lái)越受到人們的重視，尤其是以測(cè)量壓力和速度的固態(tài)壓阻式傳感器應(yīng)用**為普遍。熱電阻熱電阻測(cè)溫是基于金屬導(dǎo)體的電阻值隨溫度的增加而增加這一特性來(lái)進(jìn)行溫度測(cè)量的。傳感器（圖6）熱電阻大都由純金屬材料制成，應(yīng)用**多的是鉑和銅，此外，已開始采用鎳、錳和銠等材料制造熱電阻。熱電阻傳感器主要是利用電阻值隨溫度變化而變化這一特性來(lái)測(cè)量溫度及與溫度有關(guān)的參數(shù)。在溫度檢測(cè)精度要求比較高的場(chǎng)合，這種傳感器比較適用。較為***的熱電阻材料為鉑、銅、鎳等，它們具有電阻溫度系數(shù)大、線性好、性能穩(wěn)定、使用溫度范圍寬、加工容易等特點(diǎn)。用于測(cè)量-200℃～+500℃范圍內(nèi)的溫度。
