IMG Welcomes New Faculty Member, YK Yoon

IMG welcomes Professor YK Yoon as new faculty in the Department of Electrical and Computer Engineering. Prof. Yoon joins IMG from the University of Buffalo, The State University of New York. He has achieved numerous awards for excellence including the NSF CAREER Award and the UB's Exceptional Scholar Young Investigator Award. His research interests include MEMS and nanotechnology, RF/Microwave, millimeter wave and terahertz system, Micro/nano-biomedical devices and bio molecule (drug/vaccine/gene) delivery, µ-TAS, lab-on-a-chip, wireless/wired sensors and actuators and Metamaterial and its RF application. Prof. Yoon is also the Director of the Multidisplinary Nano and Microsystems Laboratory at UF.

Chris Meyer wins "Professional Excellence" Award

Chris Meyer has been selected by the UF College of Engineering as the 2010-2011 Ph.D. recipient of the Attributes of a Gator Engineer Recognition Award for Professional Excellence.  He was selected for "exemplifying the attribute of professional excellence with his strong record of character and performance."  Chris will be recognized by Dean Abernathy in an awards ceremony in August.

IMG Seminar: Overview of Micropillar Shear Stress Sensors

Event date: 
Fri, 08/13/2010 - 3:30pm to 4:00pm

This Friday, Jessica Sockwell will be giving a seminar on micropillar shear stress sensors. Micropillar shear stress sensors have been developed in recent years with the goal of attaining full-field shear stress measurements within turbulent boundary layers. This talk will explain how the sensors work, summarize the design and fabrication of these devices, highlight their strengths and weaknesses, and discuss how these sensors might be further improved for future use.

IMG Picosecond Laser Micromachining Workstation Online

Installation of an Oxford Lasers J-355PS Laser Micromachining Workstation has just been completed and the system is ready for use.  The tool is the first of its kind to be installed in the U.S., and provides a unique capability for IMG by enabling the machining of many different types of materials including sapphire and silicon, as well as other glasses and polymers. Purchase of this system was made possible by collaboration between Professors David Arnold and Mark Sheplak of IMG and Professor Tony Schmitz of UF's Machine Tool Research Center (MTRC).

Ultra-Miniature Power Management for Microsystem Platforms

High density passive components (inductors, transformers, capacitors) are developed and integrated with high frequency (100-500 MHz) CMOS switching power conversion circuits. The  mm3-scale integrated converter will be capable of delivering >20 V from a battery source to enable mobile microsystems such as micro air vehicles and microrobots.

High-inductance-density air core inductors and transformers have been fabricated using a three-dimensional copper electroforming process. These devices have measured inductance densities > 100 nH/mm2  and quality factors > 20. Optimal performance is achieved in the range of 50 MHz - 500 MHz to enable next generation switching converters operating at very high frequencies.
