Piezoelectric MEMS resonator for DC-DC power conversion

As power electronics push for greater miniaturization, efficiency, and integration, conventional magnetic-based passive components like inductors and transformers face fundamental scaling limitations. Piezoelectric MEMS resonators offer a promising alternative, leveraging mechanical energy storage to enable compact, high-efficiency, and magnetic-free DC-DC power conversion. Recent advancements in piezoelectric materials, MEMS fabrication, and resonator-based power electronics open new avenues for achieving ultra-compact, high-power-density converters that can outperform traditional designs. This project will focus on designing, fabricating, and characterizing a piezoelectric MEMS resonator optimized for DC-DC power conversion, investigating its efficiency, power handling, and scalability for integration into next-generation power management systems.

The student will:

• Design a MEMS piezoelectric resonator tailored for efficient DC-DC conversion.
• Fabricate the resonator using state-of-the-art MEMS processes.
• Characterize the device’s electrical and mechanical performance, evaluating its efficiency, power density, and feasibility for integration into power converter circuits.

This project is ideal for students interested in MEMS, piezoelectric materials, and next-generation power electronics, contributing to the paradigm shift in compact energy conversion technologies.
