Piezoelektrik Etki Nedir?<\/h3>\n

Piezoelektrik etki, baz\u0131 kristallerin ve seramiklerin mekanik stres alt\u0131nda elektrik y\u00fck\u00fc \u00fcretme yetene\u011fidir. Bu etki, malzemenin kristal yap\u0131s\u0131ndaki asimetrik y\u00fck da\u011f\u0131l\u0131m\u0131ndan kaynaklan\u0131r. Malzemeye bas\u0131n\u00e7 uyguland\u0131\u011f\u0131nda, bu y\u00fck da\u011f\u0131l\u0131m\u0131 bozulur ve \u00f6l\u00e7\u00fclebilir bir elektrik y\u00fck\u00fc ortaya \u00e7\u0131kar. Ters piezoelektrik etki ise, bir elektrik alan\u0131 uyguland\u0131\u011f\u0131nda malzemenin boyutlar\u0131nda bir de\u011fi\u015fiklik meydana gelmesidir.<\/p>\n

Piezoelektrik sens\u00f6rlerde kullan\u0131lan en yayg\u0131n malzemeler aras\u0131nda kuvars, turmalin, ve seramik malzemeler bulunur. \u00d6zellikle kur\u015fun zirkonat titanat (PZT) gibi seramikler, y\u00fcksek piezoelektrik katsay\u0131lar\u0131 nedeniyle tercih edilir.<\/p>\n\n\n\n\n\n\n\n

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

Bir piezoelektrik sens\u00f6r, \u00fczerine etkiyen mekanik bas\u0131nc\u0131 veya titre\u015fimi elektrik sinyaline d\u00f6n\u00fc\u015ft\u00fcrerek \u00e7al\u0131\u015f\u0131r. Bu d\u00f6n\u00fc\u015f\u00fcm, piezoelektrik malzemenin kristal yap\u0131s\u0131ndaki de\u011fi\u015fimler sayesinde ger\u00e7ekle\u015fir. Uygulamaya ba\u011fl\u0131 olarak, sens\u00f6r do\u011frudan bas\u0131nc\u0131 \u00f6l\u00e7ebilir veya titre\u015fimleri alg\u0131layarak dolayl\u0131 olarak bas\u0131n\u00e7 de\u011fi\u015fimlerini tespit edebilir. \u00d6rne\u011fin, ultrasonik sens\u00f6rlerde (baz\u0131 Beijing Ultrasonic \u00fcr\u00fcnleri gibi) piezoelektrik elementler hem ultrasonik dalgalar \u00fcretmek hem de yans\u0131yan dalgalar\u0131 alg\u0131lamak i\u00e7in kullan\u0131l\u0131r. Yans\u0131yan dalgalar\u0131n alg\u0131lanmas\u0131, mesafe veya hareketin tespit edilmesini sa\u011flar.<\/p>\n
