Piezoelektrische Materialien

Piezoelektrische Materialien erzeugen unter mechanischer Belastung eine elektrische Polarisation und zeigen umgekehrt Deformation bei angelegtem elektrischen Feld. Ursache ist die nicht‑zentrosymmetrische Kristallstruktur, etwa in PZT‑Keramiken, Quarz oder bestimmten Polymeren. Sie finden Anwendung in Aktoren, Sensoren, Energiewandlern und Ultraschalltechnik. Werkstoffwissenschaftlich sind Domänenstruktur, Kopplungskoeffizienten, Alterung und Temperatur‑ bzw. Feldstabilität zentral.
