Piezoelektrik Etki<\/h3>\n

Piezoelektrik etki, baz\u0131 kristallerin ve seramiklerin mekanik stres alt\u0131nda elektrik y\u00fck\u00fc \u00fcretme yetene\u011fidir. Bu malzemeler, bas\u0131n\u00e7, gerilme veya b\u00fck\u00fclme gibi mekanik bir kuvvete maruz kald\u0131klar\u0131nda, i\u00e7lerindeki kristal yap\u0131 deforme olur ve y\u00fczeylerinde bir elektrik y\u00fck\u00fc olu\u015fur. Bu olaya "do\u011frudan piezoelektrik etki" denir. Tersine, bu malzemelere bir elektrik alan\u0131 uyguland\u0131\u011f\u0131nda, boyutlar\u0131nda bir de\u011fi\u015fiklik meydana gelir. Bu ise "ters piezoelektrik etki" olarak adland\u0131r\u0131l\u0131r.<\/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 seramikler, y\u00fcksek hassasiyetleri ve \u00e7e\u015fitli \u015fekillerde \u00fcretilebilme yetenekleri nedeniyle yayg\u0131n olarak tercih edilir.<\/p>\n\n\n\n\n\n\n\n

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. Mekanik bir kuvvet uyguland\u0131\u011f\u0131nda, piezoelektrik malzeme deforme olur ve metal plakalar aras\u0131nda bir voltaj fark\u0131 olu\u015fturur. Bu voltaj fark\u0131, bas\u0131nc\u0131n b\u00fcy\u00fckl\u00fc\u011f\u00fc ile orant\u0131l\u0131d\u0131r ve bir \u00f6l\u00e7\u00fcm cihaz\u0131 taraf\u0131ndan okunabilir.<\/p>\n

Sens\u00f6r\u00fcn \u00c7al\u0131\u015fma Prensibi<\/h3>\n

Bir piezoelektrik sens\u00f6r, uygulanan bas\u0131nca orant\u0131l\u0131 bir elektrik sinyali \u00fcretir. Bu sinyal, bir y\u00fckseltici devre taraf\u0131ndan g\u00fc\u00e7lendirilir ve daha sonra bir mikroi\u015flemci taraf\u0131ndan i\u015flenir. Mikroi\u015flemci, sinyali kalibre eder ve bas\u0131n\u00e7, ivme veya kuvvet gibi ilgili fiziksel b\u00fcy\u00fckl\u00fc\u011f\u00fc hesaplar.<\/p>\n
