壓(ya)(ya)(ya)(ya)力(li)傳(chuan)(chuan)感(gan)器是(shi)工業實踐中(zhong)zui為常(chang)用(yong)(yong)的(de)(de)(de)(de)種傳(chuan)(chuan)感(gan)器，而(er)我們(men)通常(chang)使用(yong)(yong)的(de)(de)(de)(de)壓(ya)(ya)(ya)(ya)力(li)傳(chuan)(chuan)感(gan)器主要是(shi)利(li)用(yong)(yong)壓(ya)(ya)(ya)(ya)電(dian)(dian)(dian)(dian)(dian)效(xiao)(xiao)應制造(zao)而(er)成的(de)(de)(de)(de)，這樣(yang)的(de)(de)(de)(de)傳(chuan)(chuan)感(gan)器也稱為壓(ya)(ya)(ya)(ya)電(dian)(dian)(dian)(dian)(dian)傳(chuan)(chuan)感(gan)器。 　　我們(men)知道，晶(jing)(jing)(jing)體(ti)是(shi)各向(xiang)異性的(de)(de)(de)(de)，非晶(jing)(jing)(jing)體(ti)是(shi)各向(xiang)同性的(de)(de)(de)(de)。某(mou)些(xie)晶(jing)(jing)(jing)體(ti)介質，當(dang)沿著定(ding)方向(xiang)受(shou)到(dao)機(ji)械(xie)(xie)力(li)作用(yong)(yong)發生(sheng)(sheng)變(bian)形時(shi)(shi)，就產生(sheng)(sheng)了(le)極化(hua)(hua)效(xiao)(xiao)應；當(dang)機(ji)械(xie)(xie)力(li)撤掉之后，又(you)會重新回到(dao)不帶電(dian)(dian)(dian)(dian)(dian)的(de)(de)(de)(de)狀態，也就是(shi)受(shou)到(dao)壓(ya)(ya)(ya)(ya)力(li)的(de)(de)(de)(de)時(shi)(shi)候，某(mou)些(xie)晶(jing)(jing)(jing)體(ti)可能(neng)產生(sheng)(sheng)出(chu)電(dian)(dian)(dian)(dian)(dian)的(de)(de)(de)(de)效(xiao)(xiao)應，這就是(shi)所(suo)(suo)(suo)謂的(de)(de)(de)(de)極化(hua)(hua)效(xiao)(xiao)應。科(ke)學家就是(shi)根據這個(ge)效(xiao)(xiao)應研制出(chu)了(le)壓(ya)(ya)(ya)(ya)力(li)傳(chuan)(chuan)感(gan)器。 　　壓(ya)(ya)(ya)(ya)電(dian)(dian)(dian)(dian)(dian)傳(chuan)(chuan)感(gan)器中(zhong)主要使用(yong)(yong)的(de)(de)(de)(de)壓(ya)(ya)(ya)(ya)電(dian)(dian)(dian)(dian)(dian)材(cai)料包括有(you)石(shi)英(ying)、酒石(shi)酸鉀鈉和(he)磷酸二(er)氫(qing)胺。其(qi)中(zhong)石(shi)英(ying)（二(er)氧(yang)化(hua)(hua)硅）是(shi)種天(tian)然(ran)晶(jing)(jing)(jing)體(ti)，壓(ya)(ya)(ya)(ya)電(dian)(dian)(dian)(dian)(dian)效(xiao)(xiao)應就是(shi)在這種晶(jing)(jing)(jing)體(ti)中(zhong)發現的(de)(de)(de)(de)，在定(ding)的(de)(de)(de)(de)溫(wen)度(du)范圍(wei)之內，壓(ya)(ya)(ya)(ya)電(dian)(dian)(dian)(dian)(dian)性質直存(cun)在，但(dan)溫(wen)度(du)超(chao)過這個(ge)范圍(wei)之后，壓(ya)(ya)(ya)(ya)電(dian)(dian)(dian)(dian)(dian)性質*消失（這個(ge)高(gao)溫(wen)就是(shi)所(suo)(suo)(suo)謂的(de)(de)(de)(de)“居里點”）。由于隨著應力(li)的(de)(de)(de)(de)變(bian)化(hua)(hua)電(dian)(dian)(dian)(dian)(dian)場變(bian)化(hua)(hua)微小（也就說(shuo)壓(ya)(ya)(ya)(ya)電(dian)(dian)(dian)(dian)(dian)系數比較低），所(suo)(suo)(suo)以石(shi)英(ying)逐漸被其(qi)他的(de)(de)(de)(de)壓(ya)(ya)(ya)(ya)電(dian)(dian)(dian)(dian)(dian)晶(jing)(jing)(jing)體(ti)所(suo)(suo)(suo)替代。而(er)酒石(shi)酸鉀鈉具有(you)很大的(de)(de)(de)(de)壓(ya)(ya)(ya)(ya)電(dian)(dian)(dian)(dian)(dian)靈敏度(du)和(he)壓(ya)(ya)(ya)(ya)電(dian)(dian)(dian)(dian)(dian)系數，但(dan)是(shi)它(ta)只能(neng)在室溫(wen)和(he)濕度(du)比較低的(de)(de)(de)(de)環境(jing)下才能(neng)夠(gou)(gou)應用(yong)(yong)。磷酸二(er)氫(qing)胺屬(shu)于人(ren)造(zao)晶(jing)(jing)(jing)體(ti)，能(neng)夠(gou)(gou)承(cheng)受(shou)高(gao)溫(wen)和(he)相當(dang)高(gao)的(de)(de)(de)(de)濕度(du)，所(suo)(suo)(suo)以 已經得到(dao)了(le)廣(guang)泛的(de)(de)(de)(de)應用(yong)(yong)。
