Catalog Description:
Microelectromechanical devices (MEMS), such as pressure sensors, accelerometers, rate gyroscopes, and opto-mechanical assemblies and displays, require knowledge of a broad range of disciplines, from microfabrication to mechanics to electromagnetism. This course presents an introduction to this broad field, using examples, design projects, and hands-on labs drawn from real-world MEMS applications. Lectures will cover microfabrication technologies and process flow development, material properties, structural behavior of MEMS devices, transducers, and thermal domain. Later in the course, we will focus on case studies in MEMS, such as Digital Light Projection (DLP), micromachined accelerometers, and Film Bulk Acoustic Resonators (FBARs). Several hands-on assignments throughout the course will provide an opportunity for measurement and characterization of devices studied in class.

Required Text(s): None.

Recommended Text(s): None.
