Join us and register for the COMSOL Day Austria online event.

We invite you to a day of multiphysics modeling training, inspiring practical presentations and discussions – from your office or home office.

Expect inspiring keynote talks and discussions, as well as interesting COMSOL presentations on modeling techniques for various industry and research areas. You can ask questions at any time and the speakers will be happy to answer them.

In the Tech Cafés, you become active yourself and exchange ideas with colleagues and COMSOL engineers about your simulation projects and discuss things you've always wanted to talk about. You are welcome to prepare yourself for this! Specific questions about licensing options or modeling issues that you'd rather discuss privately with COMSOL staff can be addressed in one-to-one meetings at any time during COMSOL Day.

Design Optimization of a PZT MEMS 1D Micromirror for High-Resolution Displays

Micromirrors can be used in many fields, including light detection and ranging (lidar) systems for the automotive industry or biology for endoscopic bioimaging. Compared to well-established electrostatic and magnetic micromirrors, piezoelectric micromirrors can offer better electric power efficiency and better miniaturization abilities. In this work, we optimized a piezoelectrically actuated silicon-based MEMS micromirror for high-resolution displays. Our design relies on a previous device from Baran et al. [1] and is specifically optimized to increase its optical scan angle (θopt) and reduce its power consumption compared to the original design.
