Piezoelektrik Etki Nedir?<\/h3>\n

Piezoelektrik etki, baz\u0131 kristallerin ve seramiklerin mekanik stres alt\u0131nda elektrik y\u00fck\u00fc \u00fcretme yetene\u011fidir. "Piezo" kelimesi Yunanca "s\u0131k\u0131\u015ft\u0131rmak" veya "bas\u0131n\u00e7 uygulamak" anlam\u0131na gelir. Bu etki tersinirdir, yani malzemeye bir elektrik alan\u0131 uyguland\u0131\u011f\u0131nda fiziksel boyutlar\u0131nda bir de\u011fi\u015fiklik olur.<\/p>\n
