壓電式加速度傳感器,又稱振動傳感器,是基于壓電晶體的壓電效應(yīng)工作的。某些晶體在一定方向上受力變形時(shí),其內(nèi)部會產(chǎn)生極化現(xiàn)象,同時(shí)在它的兩個(gè)表面上產(chǎn)生符號相反的電荷;當(dāng)外力去除后,又重新恢復(fù)到不帶電狀態(tài),這種現(xiàn)象稱為“壓電效應(yīng)",具有“壓電效應(yīng)"的晶體稱為壓電晶體。常用的壓電晶體有石英、壓電陶瓷等,在現(xiàn)代生產(chǎn)生活中被應(yīng)用于許許多多的方面,如手提電腦的硬盤抗摔保護(hù),目前用的數(shù)碼相機(jī)和攝像機(jī)里,也有加速度傳感器,用來檢測拍攝時(shí)候的手部的振動,并根據(jù)這些振動,自動調(diào)節(jié)相機(jī)的聚焦。壓電加速度傳感器還應(yīng)用于汽車安全氣囊、防抱死系統(tǒng)、牽引控制系統(tǒng)等安全性能方面。
