Microelectromechanical systems (MEMS) is a growing field with numerous potential commercial applications, including pressure and inertial sensing, optical and electrical switching, power conversion, fluidic flow control, and chemical analysis. MEMS combine mechanical and electrical (and sometimes optical, chemical, or biological) function at small scales using many of the batch fabrication techniques developed for the micro-electronics industry. Materials have been developed or adapted for MEMS applications for use as structures, actuators, and sensors. Processing techniques also have been established for integrating these materials with existing MEMS. In addition, MEMS technology has proven ideal for allowing the mechanical and tribological characterization of materials at small scales. This book, first published in 2001, addresses these issues and a variety of materials are discussed, including Si, porous Si, SiC, SiGe, diamond, electroplated Ni and Cu, as well as piezoelectric, ferroelectric, and shape memory materials, and self-assembled organic monolayers. Fabrication processes include plasma and chemical etching, Si bonding, high-aspect-ratio lithography and micromolding. In addition, the stress, fracture strength, fatigue, and friction of MEMS materials and structures are also discussed.

The application of Micro Electro Mechanical Systems (MEMS) in the biomedical field is leading to a new generation of medical devices. MEMS for biomedical applications reviews the wealth of recent research on fabrication technologies and applications of this exciting technology.The book is divided into four parts: Part one introduces the fundamentals of MEMS for biomedical applications, exploring the microfabrication of polymers and reviewing sensor and actuator mechanisms. Part two describes applications of MEMS for biomedical sensing and diagnostic applications. MEMS for in vivo sensing and electrical impedance spectroscopy are investigated, along with ultrasonic transducers, and lab-on-chip devices. MEMS for tissue engineering and clinical applications are the focus of part three, which considers cell culture and tissue scaffolding devices, BioMEMS for drug delivery and minimally invasive medical procedures. Finally, part four reviews emerging biomedical applications of MEMS, from implantable neuroprobes and ocular implants to cellular microinjection and hybrid MEMS.With its distinguished editors and international team of expert contributors, MEMS for biomedical applications provides an authoritative review for scientists and manufacturers involved in the design and development of medical devices as well as clinicians using this important technology. - Reviews the wealth of recent research on fabrication technologies and applications of Micro Electro Mechanical Systems (MEMS) in the biomedical field - Introduces the fundamentals of MEMS for biomedical applications, exploring the microfabrication of polymers and reviewing sensor and actuator mechanisms - Considers MEMS for biomedical sensing and diagnostic applications, along with MEMS for in vivo sensing and electrical impedance spectroscopy

Microelectromenchanical systems (MEMS) is a revolutionary field that adapts for new uses a technology already optimized to accomplish a specific set of objectives. The silicon-based integrated circuits process is so highly refined it can produce millions of electrical elements on a single chip and define their critical dimensions to tolerances of 100-billionths of a meter. The MEMS revolution harnesses the integrated circuitry know-how to build working microsystems from micromechanical and microelectronic elements. MEMS is a multidisciplinary field involving challenges and opportunites for electrical, mechanical, chemical, and biomedical engineering as well as physics, biology, and chemistry. As MEMS begin to permeate more and more industrial procedures, society as a whole will be strongly affected because MEMS provide a new design technology that could rivalâ€"perhaps surpassâ€"the societal impact of integrated circuits.

This book is part of a popular series on the materials science of MEMS devices, first published in 1999. In the years since, many sophisticated devices have emerged and many aspects of MEMS materials behaviors have been characterized. However, there remain many basic questions about the relationship between process, properties and function for MEMS materials. Experimental methods have been developed, but there REMAINS a lack of standardization that would allow comparison between laboratories and commercial vendors or the creation of materials specifications that would enable greater commercialization of MEMS. The book addresses many of these issues including: RF-MEMS; optical MEMS; MEMS metrology, tribology, materials characterization and mechanical behavior; MEMS surfaces, MEMS reliability, packaging and life assessment; MEMS modeling and software tools for materials integration; biocompatibility of MEMS materials and devices; new materials and fabrication methodologies for MEMS; microfluidics and nanofluidics; in vivo drug/gene/protein delivery; novel actuators; MEMS cell-based systems; MEMS neural interfaces; MEMS sensors; and MEMS microengines and microfuel cells.

Presenting unified coverage of the design and modeling of smart micro- and macrosystems, this book addresses fabrication issues and outlines the challenges faced by engineers working with smart sensors in a variety of applications. Part I deals with the fundamental concepts of a typical smart system and its constituent components. Preliminary fabrication and characterization concepts are introduced before design principles are discussed in detail. Part III presents a comprehensive account of the modeling of smart systems, smart sensors and actuators. Part IV builds upon the fundamental concepts to analyze fabrication techniques for silicon-based MEMS in more detail. Practicing engineers will benefit from the detailed assessment of applications in communications technology, aerospace, biomedical and mechanical engineering. The book provides an essential reference or textbook for graduates following a course in smart sensors, actuators and systems.
