This much-needed textbook is an exploration of a key area of study in mechanics. It is suitable for senior undergraduate and graduate level students and offers a novel and systematic look into the dynamics of MEMS. A highly practical treatment of the subject, it includes numerous solved examples together with the proposed problems. The material to be found here will also be of interest to researchers with a non-mechanical background. The book focuses on the mechanical domain, specifically the quasi-static sub-domain, and provides an in-depth treatment of problems that involve reliable modeling, analysis and design.
