In this work a combination of Laser Doppler Vibrometry (LDV) and Mapping Single Beam Laser Interferometry (SBLI) was used to characterize PMUT displacement shapes at frequencies of 600 kHz and 1 kHz, respectively. Finite element modeling demonstrated excellent agreement with the displacements, once the device geometry was corrected to measured (rather than nominal) dimensions and appropriate boundary conditions were applied. Mapping SBLI was also used to characterize mechanical crosstalk at low frequencies, which is critical for evaluating PMUT performance. It was also demonstrated that driving one element induces bending of the PMUT substrate over dimensions on the 3 mm scale. The analysis of displacement profiles near the edges of released parts of PMUT structure revealed 150 μm transition regions between clamped and released areas.

Recent innovations in fabrication techniques have shown promising results in improving the density, mechanical integrity, oxidation resistance, and uniform microstructures of UHTCMCs. However, challenges like incomplete densification, porosity, and thermal shock limitations still impede their broader application. This review explores the progression of UHTCMC fabrication, focusing on both traditional and hybrid techniques and evaluating their respective advantages and shortcomings. This work also focuses on how little changes in these methods have resulted in complicated multi-phase microstructures, which show a huge improvement in customizing the outstanding performance of UHTCMCs in harsh conditions.

This concept is not easy to define because it depends on several factors including material considerations (microstructure and rheological properties), as well as process parameters that cannot be evaluated by a single metric. Some printability criteria have been proposed to classify and map the rheological properties of DIW inks. However, these criteria fail to capture all the relevant rheological aspects, and to consider DIW system technical specifications, processing parameters, and final part properties, while rheological characterisation methods remain inconsistent and lack standardisation. This review tackles this gap in the field by providing an overview of literature investigating the links between rheological properties and printability for ceramics DIW.
