Piezoverbunde vereinen die Funktionalität von Piezokeramiken als elektromechanischer Koppelwerkstoff mit der Robustheit und der Funktionalität von Strukturwerkstoffen. Signalwandlung, Stellfunktion, Spannungstransformation oder Ladungsgenerierung sind nutzbare aktive Funktionen. Die Realisierung neuer Komponenten und Strukturen mit diesen intelligenten Werkstoffeigenschaften erweitert das Spektrum möglicher Anwendungen deutlich. Beispiele sind smarte Leichtbaustrukturen mit integrierter Formkontrolle, reduzierter Schwingungsneigung und unterdrückter Geräuschemission, Form- und Positionskontrolle in adaptiven optischen Systemen, drahtlose Sensornetzwerke für die Überwachung von Strukturen, dezentrale Energieversorgung durch Energiesammlung aus mechanischen Schwingungen oder Vorort-Spannungswandlung und Ultraschallwandler mit verbesserter Effizienz und größerer Bandbreite.
Fortschritte auf diesem Arbeitsgebiet resultieren aus interdisziplinären Werkstofftechnologien, innovativen Fertigungsverfahren, neuen Entwurfsmethoden und Marktanforderungen. Das Symposium ISPA 2011 dient als Plattform für einen Informationsaustausch zu Anforderungen des Marktes, Forschungsinteressen, aktuellen Ergebnissen und Leistungsangeboten und erleichtert die Findung zukünftiger Partnerschaften. Ingenieure, Designer und Führungskräfte sind eingeladen, zu aktuellen Entwicklungen und Zukunftsplanungen zu referieren. Spezifische Themen können in der Poster-Session vorgestellt werden. Die Tagung wird zudem durch eine Industrieausstellung abgerundet.

Piezocomposites combine the functionality of piezoceramics as electromechanical transducer material with the robustness and functionality of complementary constituent materials. Sensing, actuation, voltage transformation, or charge generation are usable active properties. The creation of new components and structures with these intelligent material properties radically extends the spectrum of applications. Examples are smart lightweight structures of controlled shape, reduced vibration or suppressed noise, shape and position control in adaptive optical systems, wireless sensor networks for structural health monitoring, decentralized power supply by energy harvesting form mechanical vibrations or on site voltage transformation, and ultrasonic transducer with improved efficiency and larger bandwidth. Progress in the field arises from cross-discipline material technologies, innovative production technologies, design skills and market requirements.
The symposium ISPA 2011 intends to serve as a platform enabling an exchange of information on market requirements, research interests and current results, skills and resources and facilitating the building of future partnerships.
