Brock Peterson was born and raised in the Seattle, Washington area. Brock received his B.S. in Electrical Engineering from Brigham Young
University in August 2010. At BYU, he was involved in research
studying sodium-based MRI designing RF resonant coils. Since then he
has been pursuing his M.S. and Ph.D. degrees at Georgia Tech. Brock
began his research with the MicroSensors and MicroActuators group in
May 2011. The focus of his research has been on laser machined
micromagnets and the applications of highly oscillating, strong
magnetic field patterns.
Research: Permanent-magnet MEMS devices
High-energy-product rare-earth magnetic materials (such as SmCo and NdFeB alloys) have enabled or enhanced many application areas. In recent years, MEMS-scale applications have fueled interest in sub-millimeter microsctructured magnetics, where the overall magnet size or features on the magnet may range from micrometers to hundreds or micrometers. In addition, some applications of MEMS devices require a high-spatial-frequency magnetic field (Applications include microgenerators, actuators, microundulators,...). We are developing such magnetic structures using a combination of laser micromachining and advanced assembly technologies. The image shows a SmCo array featuring 50 400-micron-long periods of alternating magnetic field. More...
