Ofer Rozen, Ph.D. 2015

Mechanical and Aerospace Engineering
Advisor: Prof. Horsley
(530) 219 8461
Research Interests: Mechanical and system design of micro-electro-mechanical system (MEMS) products. Integrated engineering of MEMS-based products from chip to package. Conceptual and detailed design, modeling, packaging and assemblies, that allow novel applications of MEMS components. Design of MEMS actuators and sensors: physical sensors, microfluidics devices, switches and deformable mirrors.
Job Interests: post-doc, industry R&D

Ofer studied aerospace engineering in the Technion, Israel and recived her BSc and MSc in 2008 and 2012 respectively. Her MSc Thesis was about "Design, Manufacturing and Characterization of Micro-Scale Flapping Wings".
Ofer is pursuing a Ph.D in Mechanical Engineering at UC Davis, under Professor Horsley. She studies air coupled piezoelectric ultrasonic transducers.

Air-Coupled Piezoelectric Micromachined Ultrasound Transducers [BPN466]
Characterize air-coupled aluminum nitride piezoelectric micromachined ultrasound
transducers (pMUTs) for use in range finding and gesture recognition applications. MEMS Aluminum
Nitride (AlN) piezoelectric sensor technology has been chosen due to the relatively simple
deposition process and compatibility with CMOS technology which enables the potential
integration of the sensor and drive electronics on the same chip. Guided by both analytic and
finite element models the optimum design parameters are chosen to obtain the desired resonant
frequency, bandwidth, and maximum output sound pressure for the transmitter, and maximum
sensitivity for the receiver. We are currently exploring several conceptual designs, using
different fabrication processes, to improve robustness while maintaining the performance.
