Micron-scale magnetic motors
MEng student wanted for design, prototyping, and testing of micron-scale magnetic field actuators based on piezoelectric and magnetostrictive materials. Potential applications include adaptive optics, sensors, microfluidic pumps/valves, and medical devices. Design work may involve both static and dynamic finite element models of complex magnetoelastic MEMS structures using multiphysics software such as COMSOL. Microfabrication and characterization will require working in the Cornell Nano-Scale Science and Technology Facility (CNF) and Cornell Center for Materials Research (CCMR), and will include photolithography, thin film deposition and etching, and development of new fabrication processes. Solid understanding of basic electromagnetism, basic circuits, and mechanics of materials is necessary. Some experience with finite element analysis is preferred. Recommended to take MAE/ECE 4320 Micro-Electromechanical Systems, Fall 2013.
