Piezoelektrik Etki Nedir?<\/h3>\n

Piezoelektrik etki, belirli kristallerin ve seramiklerin mekanik stres alt\u0131nda elektrik y\u00fck\u00fc \u00fcretme yetene\u011fidir. Ters piezoelektrik etki ise, bu malzemelere elektrik alan\u0131 uyguland\u0131\u011f\u0131nda \u015fekillerinde bir de\u011fi\u015fiklik (genle\u015fme veya b\u00fcz\u00fclme) meydana gelmesidir. Bu iki etki birbirini tamamlar ve piezoelektrik transd\u00fcserlerin \u00e7al\u0131\u015fma prensibini olu\u015fturur.<\/p>\n
