Piezoelektrik Etki Nedir?<\/h3>\n

Piezoelektrik etki, baz\u0131 kristallerin ve seramiklerin mekanik bir kuvvete maruz kald\u0131klar\u0131nda elektrik y\u00fck\u00fc \u00fcretme yetene\u011fidir. Bu etki, malzemenin kristal yap\u0131s\u0131ndaki de\u011fi\u015fikliklerden kaynaklan\u0131r. Bas\u0131n\u00e7 uyguland\u0131\u011f\u0131nda, kristal yap\u0131s\u0131 deforme olur ve bu da y\u00fczeyinde bir elektrik y\u00fck\u00fc olu\u015fmas\u0131na neden olur. Tersine, bu malzemelere bir elektrik alan\u0131 uyguland\u0131\u011f\u0131nda, boyutlar\u0131nda bir de\u011fi\u015fiklik meydana gelir.<\/p>\n

Piezoelektrik Malzemeler<\/h3>\n

Piezoelektrik sens\u00f6rlerde kullan\u0131lan en yayg\u0131n malzemeler kuvars, turmalin ve seramiklerdir. \u00d6zellikle kur\u015fun zirkonat titanat (PZT) gibi piezoelektrik seramikler, y\u00fcksek hassasiyetleri ve d\u00fc\u015f\u00fck maliyetleri nedeniyle yayg\u0131n olarak tercih edilir.<\/p>\n\n\n\n\n\n\n\n

Piezo Sens\u00f6r\u00fcn Yap\u0131s\u0131<\/h3>\n

Bir piezoelektrik sens\u00f6r, tipik olarak iki metal plaka aras\u0131na s\u0131k\u0131\u015ft\u0131r\u0131lm\u0131\u015f bir piezoelektrik malzemeden olu\u015fur. Bu plakalar, \u00fcretilen y\u00fck\u00fc toplamak i\u00e7in elektrot g\u00f6revi g\u00f6r\u00fcr. Sens\u00f6re bir kuvvet uyguland\u0131\u011f\u0131nda, piezoelektrik malzeme deforme olur ve plakalar aras\u0131nda bir voltaj fark\u0131 olu\u015fturur. Bu voltaj, uygulanan kuvvetle orant\u0131l\u0131d\u0131r ve \u00f6l\u00e7\u00fclerek kuvvetin b\u00fcy\u00fckl\u00fc\u011f\u00fc belirlenebilir.<\/p>\n
