Bringing together the creative talents of electrical, mechanical, optical and chemical engineers, materials specialists, clinical-laboratory scientists, and physicians, the science of biomedical microelectromechanical systems (Bio MEMS) promises to deliver sensitive, selective, fast, low cost, less invasive, and more robust methods for diagnostics, individualized treatment, and novel drug delivery. The goals of this course are to introduce microfabrication, microfluidics, sensors, actuators, drug delivery systems, micro total analysis systems and lab-on-a-chip devices, detection and measurement systems. The main focus is on the fundamental challenges and limitations involved in designing and demonstrating BioMEMS devices.
ME 681:Applications of Advanced Micro/Nano Materials, Structures and Devices
The goals of this course are to go beyond the introduction stage in Micro-Electro-Mechanical Systems (MEMS) and Nano-Electro-Mechanical Systems (NEMS) to provide students with a strong background in the design and characterization of micro- and nano-scale sensors and actuators with a broad range of applications in VNT-based sensors, actuators and devices, biomedical systems, micro- and nanoscale manipulation, adaptive optics, and microfluidics. The main focus is on the fundamental challenges and limitations involved in designing and demonstrating micro and nano devices and systems. Prerequisites: ME 573, ME 581 or equivalent.
