The Interdisciplinary Microsystems Group (IMG) is a college-wide multi-departmental education and research program of the College of Engineering at the University of Florida.
John Rogers will defend his proposal entitled "A passive wireless MEMS dynamic pressure sensor with integrated temperature compensation for harsh environments" at 11:45 AM on Friday, October 9th, in Larsen 234.
Lunch will be provided for $3 to those who sign up on the IMG wiki (http://www.img.ufl.edu/wiki/index.php/IMG_Seminar_Series:_Fall_2015)
Ololade Oniku will defend his Dissertation entitled “Electroplated Thick-Film Cobalt Platinum Permanent Magnets” on Thursday, September 24, 2015 at noon in NRF 115. Lunch will be provided.
Dr. Nishida will present the Multi-functional Integrated System Technology (MIST) Center, a NSF Industry/University Cooperative Research Center led by the University of Florida (UF) with founding partner site, University of Central Florida (UCF), focused on the hardware technologies necessary to propel the next generation of smart mobile sensing/computing/communication systems. The MIST Center is motivated by three major research/industry trends: (1) stepping beyond the current challenge of continued conventional scaling of integrated circuits, a.k.a. Moore's Law, (2) exploring new functionalities at intersections of materials/ processes/ devices /circuits for multi-functional systems, and (3) integrating nanoscale materials into micro/nanosystem manufacturing.
Patrick Lomenzo will present on ferroelectricity in HfO2-based thin films:
Ferroelectricity in HfO2-based thin films offers an intriguing pathway toward the realization of ferroelectric devices for next generation memory technologies. Understanding the reliability characteristics and underlying defects of HfO2 ferroelectrics is of critical importance for its successful adoption in emerging memory devices. The observation of asymmetric ferroelectric properties of HfO2 thin films with TaN electrodes is discussed in the context of charged defects and the chemical properties of the electrode interfaces.
Dr. Tabrizian will present an overview of semiconductor micromechanical resonators and acoustic phonon traps. The phonon-level formulation of vibration modes and dissipation mechanisms will be described. Performance sensitivity of phonon traps to physical interactions will be discussed and followed by demonstration of several applications in environmental sensing and physical gauging. Moreover, temperature and dissipation compensation techniques for realization of highly-stable low-loss micro-resonators for frequency reference purposes will be reviewed.
IMG welcomes Dr. Roozbeh Tabrizian as a new faculty member in the Department of Electrical and Computer Engineering. Dr. Tabrizian received the BS in Electrical Engineering from Sharif University of Technology, Tehran, Iran, in 2007, and the PhD in Electrical and Computer Engineering from Georgia Institute of Technology, 2013. He was then a Post-doctoral research fellow in the Electrical Engineering and Computer Science department at University of Michigan. Roozbeh’s research has resulted in more than 25 journal and conference papers, and 6 patents. His research activities are focused on theoretical and experimental investigation of mixed-domain physical devices such as sensors, actuators, resonators and energy harvesters, and development of micro and nanofabrication techniques for large-scale integration of microsystems.
Please join us for our annual IMG Kickoff Meeting at 11:30am in Larsen 310. This meeting is required for all IMG personnel. Pizza will be served.
Camilo Velez Cuervo was awarded "Best Poster" for "Analysis of Microscale Permanent Magnets for Capturing Magnetic Particles in Biological Fluids" at the 2015 Frontiers in Biomagnetic Particles Conference in Telluride, CO. Congratulations to Camilo, Alexandra, and other co-authors!
The UF Smart Mouthguard team won 2nd place in the International Contest of Applications in Nano/Micro Technologies (iCAN 2015).
iCAN is an international competition for college students, to promote the innovative spirits of youth, to construct collaboration platforms, and to increase applications of nano-micro technology. More than 15,000 students participated in the contest and 19 finalist teams from 12 countries were invited to the finals held in Anchorage, AK, June 20 - 22, 2015. The UF team represented the USA and won 2nd place out of the 19 finalist teams.
The UF team included
Students: Justin Correll (ECE, Undergrad), Tim Ajmani (ECE, Undergrad), Troy Templin (BME, Undergrad), Sheng-Po Fang (ECE, Graduate)
Advisors: YK Yoon (ECE), Fong Wong (Dentistry), Huikai Xie (ECE)
