Advisor: Prof. Lin
(510) 642-8983
Research Interests: Design and Fabrication of Micro-Electro Mechanical Sensors and Actuators; Piezoelectric Micromachined Ultrasonic Transducers; MEMS-based Resonators.

Sina Akhbari is currently a Ph.D. candidate in the Department of Mechanical Engineering at UC Berkeley. He received his B.Sc. (2012) in Mechanical Engineering from Sharif University of Technology, Tehran, Iran. He received his M.Sc. (2014) from the University of California at Berkeley as part of his PhD program and advanced toward PhD candidacy in the same year. He has been working on design and fabrication of MEMS Resonator Gyroscopes and Piezoelectric Micromachined Ultrasonic Transducers (pMUTs) as part of Ph.D. research.

Highly Responsive pMUTs [BPN743]
Ultrasonics has been realized as a nondestructive measurement method for a variety of applications,
such as: medical imaging, healthcare monitoring, nondestructive testing, range finding, motion
sensing ,and etc. In addition, high intensity ultrasound can be used in therapeutic treatments,
such as: lithotripsy for kidney stone comminution, hyperthermia for cancer therapy, high-intensity
focused ultrasound (HIFU) for laparoscopic surgery, and transcranial sonothrombolysis for brain
stroke treatment.
MEMS ultrasound transducers are known to have several advantages over the conventional ultrasound
devices, such as: higher resolution, higher bandwidth, and lower power consumption. The main purpose
of this project is to develop new architectures of Piezoelectric Micromachined Ult1rasonic
Transducers (pMUT) with higher electromechanical energy efficiency and higher sensitivity using CMOS
fabrication technology, which make them suitable for battery power handheld devices. The specific
focus is on power-efficient hand-held medical devices for diagnosis/therapy with high acoustic
intensity and high frequency bandwidth requirements.
