Master Thesis - Characterization of Piezoelectric Micromachined Ultrasonic Transducers (PMUTs) (f/m/d)

YOUR FUTURE RESPONSIBILITIES:
Recently, a new series of PMUTs for biomedical and industrial applications have been designed and fabricated, which is a further extension to our previous work (Appl. Phys. Lett. 115, 023501 (2019); https://doi.org/10.1063/1.5097624). This thesis aims at a full-range characterization of PMUTs with regard to the electrical, piezoelectric, mechanical, thermofluidic, acoustic, and material properties. After the characterization, a simple demonstrator based the PMUT will be built. The analysis and summary on the characterization results will contribute to the optimization of next-generation PMUTs.
