Kev Taw Qhia Txog Ultrasonic Sensors
Cov sensors ultrasonic yog cov sensors tsim los ntawm kev siv cov yam ntxwv ntawm ultrasound. Cov sensors ultrasonic siv cov nyhuv piezoelectric ntawm piezoelectric ceramics. Thaum lub teeb liab hluav taws xob raug siv rau lub phaj piezoelectric ceramic, nws yuav deform, ua rau lub sensor co thiab tso tawm cov nthwv dej ultrasonic. Thaum ultrasound ntaus ib qho teeb meem, nws cuam tshuam rov qab thiab ua rau ntawm lub phaj piezoelectric ceramic los ntawm lub sensor. Raws li cov nyhuv piezoelectric rov qab, lub sensor ultrasound tsim cov teeb liab hluav taws xob tso tawm. Los ntawm kev siv lub hauv paus ntsiab lus ntawm qhov ceev ntawm cov nthwv dej ultrasonic hauv tib lub nruab nrab, qhov deb ntawm cov teeb meem tuaj yeem txiav txim siab raws li lub sijhawm sib txawv ntawm kev xa thiab txais cov teeb liab. Cov nthwv dej ultrasonic yuav tsim cov suab rov qab tseem ceeb thaum lawv kov cov khoom tsis huv lossis cov interfaces, thiab cov teebmeem Doppler thaum lawv kov cov khoom txav mus los. Yog li ntawd, cov sensors ultrasonic tau siv dav hauv kev lag luam, kev siv pej xeem, kev tiv thaiv lub tebchaws, biomedicine, thiab lwm yam teb.
