Materiali ferroelettrici, antiferroelettrici, piezoelettrici

Responsabili: Elisa Mercadelli

Personale coinvolto: Carmen Galassi, Claudio Capiani, Carlo Baldisserri, Paola Pinasco

La ricerca sui materiali perovskitici con proprietà ferroelettriche, antiferroelettriche, piezoelettriche spazia dall’ottimizzazione dell’intero processo di produzione del dipositivo (dalla sintesi delle polveri, al loro processo di formatura/sinterizzazione e successiva caratterizzazione funzionale) allo lo studio dei fenomeni fisici alla base delle loro peculiari prestazioni nell’ambito di consolidate collaborazioni nazionali e internazionali.
In questa direzione, CNR-ISTEC è un punto di riferimento a livello nazionale ed internazionale in virtù della consolidata esperienza nella produzione di componenti attivi (polarizzati) da integrare nella meccanica ed elettronica dedicata.

Composizioni in cui coesistono fasi ferroelettriche e antiferreolettriche vengono attualmente ri-scoperte per l’accumulo di energia, attuatori ad alta deformazione, effetto elettrocalorico.

Vengono sviluppati materiali e componenti piezoelettrici nei sistemi zirconato/titanato di piombo (PZT) e lantanio, (PLZT), ma soprattutto senza piombo, quali bismuto sodio bario titanato (BNBT), bario stronzio titanato (BST), potassio-sodio niobati (KNN) e bario-calcio titanati-zirconati (BCTZ) mediante sintesi allo stato solido e metodi chimici.

Vengono sviluppati componenti massivi (densi o porosi), film spessi, per applicazioni specifiche a bassa ed alta potenza in un ampio intervallo di frequenze.

Possono essere sviluppati (progettati e realizzati) prototipi di attuatori e sensori piezoelettrici massivi e multistrato, trasformatori di tensione, trasduttori.

Campi di applicazione: soppressione attiva di vibrazione, recupero di energia meccanica, acustica subacquea, dispositivi indossabili etc..
