IMG Seminar

MAE Seminar: Microfluidics and Enabling Components

Event date: 
Tue, 08/31/2010 - 8:00pm

IMG's own Dr. Z. Hugh Fan will give a Mechanical and Aerospace Engineering department seminar entitled Microfluidics and Enabling Components.

Microfluidics is to study fluids at the microscale. It is a field that promises to reach the holy grail of "lab-on-a-chip". In analogy to shrinking a computer from the size of a room in the 1950s to a laptop today, instruments for chemical and biological analyses may be miniaturized into microfluidic devices using modern microfabrication technology.

IMG Seminar: An Input-powered AC/DC Converter with Zero Standby Power for Energy Harvesting Applications

Event date: 
Wed, 09/01/2010 - 7:00pm to 7:30pm

Energy harvesting techniques require more reliable power electronics. Conventional AC/DC converters in energy harvesting systems are normally self-powered by their load-sided energy storage elements. This feature makes the storage elements easily drained and the whole system may no longer be able to function. An input-powered AC/DC converter is proposed to eliminate the need for pre-charging the load and allows for infinitely long intervals from the energy harvester.

Note: Drinks and snacks will be served for Fall lMG seminars.

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.
