Interdisciplinary Microsystems Group
University of Florida
This talk will highlight my group's development of microfabricated permanent magnets and their application in several functional microsystems. To set the stage, I'll first describe some basic concepts about magnets and physical scaling laws that motivate our efforts. I'll then discuss our advancement of two types of permanent magnet materials--electroplated layers and bonded powders, which overcome certain manufacturing and integration challenges. I'll then showcase how these permanent magnet materials are being used for electromechanical actuators, energy harvesting devices, and generation of high-energy x-rays.
David P. Arnold is currently an Associate Professor in the Department of Electrical and Computer Engineering at the University of Florida and a member of the Interdisciplinary Microsystems Group. He received dual B.S. degrees in electrical and computer engineering in 1999, followed by the M.S. degree in electrical engineering in 2001, from the University of Florida. He received the Ph.D. degree in electrical engineering from the Georgia Institute of Technology in 2004. His research focuses on micro/nanostructured magnetic materials, magnetic microsystems, electromechanical transducers, and miniaturized power/energy systems. He is an active participant in the magnetics and MEMS communities, and currently serves on the editorial boards of /J. Micromechanics and Microengineering/ and /Energy Harvesting and Systems/. He has co-authored over 125 refereed journal and conference publications, and holds six U.S. patents. His research innovations have been recognized by the 2008 Presidential Early Career Award in Science and Engineering (PECASE) and the 2009 DARPA Young Faculty Award. He is a Senior Member of IEEE and also a member of Tau Beta Pi, and Eta Kappa Nu. Beyond his passion for research and teaching, he most enjoys spending time with his wife and three children.
