Understanding Mems: Principles and Applications by Luis Castañer

By Luis Castañer

The ongoing development of MEMS (micro-electro-mechanical platforms) complexity, functionality, advertisement exploitation and industry dimension calls for an ever-expanding graduate inhabitants with state of the art expertise.

"Understanding MEMS: ideas and purposes "provides a accomplished creation to this complicated and multidisciplinary expertise that's obtainable to senior undergraduate and graduate scholars from a variety of engineering and actual sciences backgrounds.

Fully self-contained, this textbook is designed to assist scholars seize the foremost ideas and operation of MEMS units and to encourage complex examine or a occupation during this field.

Moreover, with the expanding software parts, product different types and performance of MEMS, pros also will take advantage of this consolidated evaluate, resource of appropriate equations and large suggestions to problems.

Key gains: information the basics of MEMS, permitting readers to appreciate the fundamental governing equations and understand how they observe on the micron scale. robust pedagogical emphasis allowing scholars to appreciate the basics of MEMS units. Self-contained research relief that includes difficulties and suggestions. ebook significant other site hosts Matlab and PSpice codes and viewgraphs.
