Introduction to MEMS

Nestled within our smartphones automobiles medical devices and industrial systems are microscopic machines-Microelectromechanical Systems or MEMS-that sense actuate and control the environment around us. This book Introduction to MEMS is designed to be the comprehensive guide on understanding with interdisciplinary technology providing a structured and thorough foundation in the principles and practices that underpin this dynamic field. This text is structured to logically build knowledge from the ground up mirroring the development process of a MEMS device itself. We begin by defining the field and its unique characteristics establishing the what and why of MEMS technology. From there we delve into the fundamental physics of MEMS mechanics providing the essential toolkit of stress strain and material properties needed to understand device behaviour. The core of the book is dedicated to the intricate world of MEMS fabrication with dedicated chapters walking through each critical steps: Deposition Techniques Photolithography LIGA Etching Bonding Micromachining processes 3D Printing MEMS polymers and sensors.
