Piezoelectric MEMS microphone for low-power applications

With the increasing demand for energy-efficient audio systems, this project aims to develop a piezoelectric MEMS microphone optimized for low-power noise cancellation in earbuds. The student will explore novel transducer concepts, focusing on enhancing sensitivity and signal-to-noise ratio while minimizing power consumption. The assignment includes literature review, the design and finite element simulation of the MEMS microphone structure, evaluating its acoustic and electrical performance. The project will also investigate potential fabrication feasibility and integration strategies. This work is ideal for students interested in MEMS design, piezoelectric materials, and acoustics.
