We present the entire process of developing a piezoelectric microprobe which was derived at the University of Split,Faculty of Science as a continuation of the MEM Split project. PMN-PT(Pb(Mg1/3Nb2/3)O3PbTiO3) thick film was used as a sample. The samples were synthesized by the sol-gel technique at the Institute Jožef Stefan Ljubljana, Slovenia. Structural analysis by X-ray diffraction has shown a high sample quality with thicknesses of 30 µm. Measurements with a scanning electron microscope have shown a grainy structure and porosity of the films with grain sizes around 5 µm. Electrical analysis confirmed the success of polarisation of the sample. Hysteresis curve was measured using a Sawyer-Tower circuit. The resonant frequency of the piezoelectric was measured at 28.5 MHz. Possibilities of developing a microprobe using methods of photolithography were investigated for two different concepts of the photomask. One concept was a microprobe with a linear kerfed array of piezoelectric elements and was rejected due to the inability of anisotropic chemical etching of PMN-PT. The second concept does not involve etching of the thick film. A rectangular area of the piezoelectric was polarised and electrodes were microstructured on top of it. Using photolithographic processes of lift-off and chemical etching the sample was prepared, polarised and electrodes for exciting the acoustic signal were microstructured on top. Due to the porosity of the film and contamination by chemicals used during the process, some electrodes cracked, which temporarily stopped further analysis. The next step would be to analyse the interference between the ultrasound elements and measurement of the acoustic properties of the microprobes.
