Weiches PZT Piezokeramikmaterial

Basisinformation

    Modell: Soft PZT

Produktbeschreibung

Weiche PZT

Hochempfindliche oder "weiche" Keramiken weisen eine hohe Empfindlichkeit und Permittivität auf, können jedoch unter Bedingungen mit hohem Antrieb über ihren Betriebstemperaturbereich hinaus selbsterhitzt werden. Diese Materialien werden in verschiedenen Tonabnehmern und Sensoren, Motorwandlern mit geringem Stromverbrauch, Empfängern und Generatoren mit geringem Stromverbrauch verwendet.



Die ideale Anwendung von weichen Piezomaterialien ist die Erfassung von Anforderungen.
