PhD Position Characterization of bi‐stable PiezoMEMS for acoustic application
TU Wien is located in the heart of Europe, in a cosmopolitan city of great cultural diversity. Our identity as a research university means that we build our reputation through our research. TU Wien combines basic and applied research and research‐oriented teaching at the highest level.
The group of Prof. Ulrich Schmid at the Institute of Sensor and Actuator Systems invites applications for a 3.5‐year PhD position (starting October 1st, 2022) in the field of piezoelectric bi‐stable MEMS design and fabrication as well as in the field of mechanical and acoustic characterization of bi‐stable PiezoMEMS.
The Project
In most cases, MEMS devices are operated either in the linear regime or close to bifurcation for enhanced sensitivity and noise performance. Operating such devices far in the bifurcation region on the other hand opens up unique and exciting new opportunities and challenges for MEMS. One such opportunity is the realization of miniaturized acoustic transducers, which take advantage of the ability to switch between bi‐stable ground states by utilizing integrated piezoelectric transducers. One major challenge lies in understanding the non‐linearities in the mechanical behavior of such bi‐stable structures.
In this project, we will investigate the bifurcation region to obtain a fundamental understanding of bi‐stable PiezoMEMS for acoustic applications in air. We will focus on the static and dynamic behavior of bi‐stable PiezoMEMS structures and the impact of their characteristics on the acoustic performance of acoustic transducers based on this technology.
The PhD candidate will be part of a team of other PhD students and PostDocs, all working in the field of PiezoMEMS. He or she will learn the intricacies of MEMS fabrication and design bi‐stable MEMS with integrated transducers (piezoelectric, electromagnetic). He or she will fabricate the designed MEMS using state‐of‐the‐art silicon microfabrication equipment in modern cleanroom facilities at TU Wien. The PhD candidate will design and build a measurement setup for both external and parametric excitation of these devices to fully characterize their mechanical behavior far in the bifurcation region. Finally, sound generation of bi‐stable PiezoMEMS acoustic transducers in non‐switching mode for applications in the audible range will be studied. All measurements will be done with modern, state‐of‐the‐art measurement tools.
For more information about the project please contact the principal investigator Ass.‐Prof. Dr. Michael Schneider (michael.schneider@tuwien.ac.at).
