Miniaturised Ultrasonic, Engineered-Structure and LTCC-Based Devices
Minuet's objective was to develop improved multifunctional, knowledge-based materials; new production processes and technologies for complex miniaturised functional structures and devices, based on electroceramics.
WP1 Materials and WP2 Integrated Multilateral Structures work closely together inapt on modelling of material properties as a function of compositions. In WP2, PZT, lead-free and the new-modelled compositions have been used to adapt frontier technologies, as LTCC structures, opening an opportunity for complex miniaturised devices. Presently, LTCC includes only passive components due to high reactivity of piezoelectric thick films with substrates. Modelling results have been verified at laboratory scale through preparation of powders and components and testing their properties. Best compositions have been scaled up and samples delivered to the end users in traditional form and in thick-film structures. The best ones have been modified further to comply with LTCC. LTCC structures can replace bulk components leading to enhanced performance with more degrees of functionality in robotics and integrated sensors (WP5 Devices for Robotics). WP3Devices for Fluidics and Optics covers work on engineered-engineered structure for adaptive "photon crystals", unable filters and print heads with discrete assemblies replaced by integrated structures. WP4 Devices for Acoustics covers medical, NDT and process control applications.
Models were used to calculate material specifications for WP1 and WP2 and design prototype devices to verify the models and test performance. MINUET had a vertical structure from material modelling to small-scale testing of compositions and technology, scaling up and testing devices. The output is the verified model and technology of new materials, their integration into LTCC, devices based upon these and engineered-engineered structures. High socio-economic potential results from reduced environmental impact by using less hazardous chemicals.

The main project outputs were:
- theoretical model for predicting stability of perovskite phases and to a certain extent the piezoelectric properties;
- new perovskite-based compositions with high permittivity (relaxor-ferroelectrics);
- extended line of lead-free piezoceramics of the alkali niobates family;
- technology for manufacturing these materials, and their integration into thick-film structures;
- technology for materials with controlled microstructure and porosity;
- devices based on all the above mentioned materials and technology for medical diagnostics and therapy, NDT, environmental monitoring, robotics and optics applications.
