MSc thesis project proposal
Piezoelectric MEMS Ultrasound Transducer (PMUT) with high sensitivity for fingerprint sensors
Ultrasound-based fingerprint sensing is a promising technology for secure and high-resolution biometric authentication. This project focuses on the development of a high-sensitivity piezoelectric micromachined ultrasound transducer (PMUT) optimized for fingerprint sensing applications. The student will conduct a literature review to assess state-of-the-art PMUT designs, followed by the design and simulation of a novel transducer structure. The project also includes fabrication and experimental characterization to evaluate key performance metrics such as sensitivity, bandwidth, and resolution. This project is ideal for students interested in design optimization, MEMS fabrication, and characterization.
