ECE 59500 - MEMS II: Fundamentals of MEMS Design

Lecture Hours: 3 Credits: 1

This is an experiential learning course.

Counts as:
CMPE Special Content Elective
EE Elective

Experimental Course Offered: Fall 2019

Requisites:
PHYS 27200 or equivalent

Catalog Description:
This course is the second 1-credit module in a 3-module series. This module introduces the fundamentals of MEMS design. We begin with the design and analysis of micromechanical springs most commonly used in successful MEMS devices. Next, we investigate popular transduction mechanisms, which allow the needed conversion of energy between electrical signals and mechanical motion (and vice versa). This is a critical component of all MEMS actuators and sensors. The course focuses primarily on electrostatic and piezoelectric transduction. Modeling of MEMS devices is then considered, with focus on linearized models and electromechanical resonance.

Supplementary Information:
This course is the second 1-credit module in a 3-module series that runs the second five weeks of the semester.
