Abstract
For the next device generation (micromotors,actuators,sensors..), classical PZT materials cannot satisfy the demands for a wide variety of actuator applications: exceptionally high piezoelectric coefficients, high electromechanical coupling coefficients and high dielectric permittivity. Relaxor-ferroelectric solid solutions are now considered as the best candidates for these applications. Improved properties of relaxor ceramics will be investigated through exploration of diagrammes between relaxor materials, new powder processing such as controlled dispersion, sol-gel synthesis, control of ceramic microstructure using new methods to prepare textured ceramics by hot forging, casting. Advanced material will be up-scaled and promoted in the European market through an end-users group and two test vehicles, Sonar transducer & Inkjet printer head, will be built.
