Piezoelektrik Etkinin Ke\u015ffi ve Tarih\u00e7esi<\/h3>\n

Piezoelektriklik, 1880 y\u0131l\u0131nda Pierre ve Jacques Curie karde\u015fler taraf\u0131ndan ke\u015ffedildi. Kuvars kristalleri \u00fczerinde yapt\u0131klar\u0131 deneylerde, kristallere uygulanan bas\u0131nc\u0131n elektrik y\u00fck\u00fc \u00fcretti\u011fini g\u00f6zlemlediler. Bu ke\u015fif, "piezo" kelimesinin Yunanca "s\u0131k\u0131\u015ft\u0131rmak" anlam\u0131na gelmesinden t\u00fcretilen "piezoelektriklik" teriminin ortaya \u00e7\u0131kmas\u0131na yol a\u00e7t\u0131. 20. y\u00fczy\u0131l\u0131n ba\u015flar\u0131nda, piezoelektrik etki sonar sistemlerinde kullan\u0131lmaya ba\u015fland\u0131 ve bu da malzemenin daha geni\u015f \u00e7apta ara\u015ft\u0131r\u0131lmas\u0131n\u0131 ve geli\u015ftirilmesini tetikledi.<\/p>\n

Piezoelektrik Etkinin \u00c7al\u0131\u015fma Prensibi<\/h3>\n

Piezoelektrik etki, malzemenin kristal yap\u0131s\u0131ndaki asimetrik y\u00fck da\u011f\u0131l\u0131m\u0131ndan kaynaklan\u0131r. Malzemeye mekanik bir kuvvet uyguland\u0131\u011f\u0131nda, bu y\u00fck da\u011f\u0131l\u0131m\u0131 bozulur ve malzemenin y\u00fczeyinde bir elektrik y\u00fck\u00fc olu\u015fur. Tersine, bir elektrik alan\u0131 uyguland\u0131\u011f\u0131nda, kristal yap\u0131daki iyonlar yer de\u011fi\u015ftirir ve bu da malzemenin boyutlar\u0131nda bir de\u011fi\u015fikli\u011fe neden olur.<\/p>\n
