Chemical Sensors 9 And Mems Nems 9

This issue of ECS Transactions is a compilation of papers presented at the 218th Meeting of the Electrochemical Society, held in Las Vegas from October 10 - 15, 2010. The papers presented covered the research and development in the field of chemical (gas, ion, bio and other) sensors, including molecular recognition surface, transduction methods, and integrated and micro sensor systems, as well as all aspects of MEMS/NEMS technology, including micro/nanomachining, fabrication processes, packaging, and the application of these structures and processes to the miniaturization of chemical sensors, physical sensors, biosensors, miniature chemical analysis systems and other devices.

The latest developments in chemical and biological sensor research and development. Topics include: 1. new selective species recognition surfaces and materials; 2. molecular recognition materials and approaches to minimize non-specific binding; 3. semi-selective species recognition materials; 4. novel methods for signal processing, signal amplification, and detection; 5. detection systems for multiple analytes in complex samples; 6. sensor arrays; and 7. analytical systems and approaches.

The papers included in this issue of ECS Transactions were originally presented in the symposium ¿Microfabricated and Nanofabricated Systems for MEMS/NEMS 8¿, held during the PRiME 2008 meeting of The Electrochemical Society, in Honolulu, Hawaii, from October 12 to 17, 2008.

This book explores the fabrication of soft material and biomimetic MEMS sensors, presents a review of MEMS/NEMS energy harvesters and self-powered sensors, and focuses on the recent efforts in developing flexible and wearable piezoelectric nanogenerators. It also includes a critical analysis of various energy harvesting principles, such as electromagnetic, piezoelectric, electrostatic, triboelectric, and magnetostrictive. This multidisciplinary book is appropriate for students and professionals in the fields of material science, mechanical engineering, electrical engineering, and bioengineering.

Recently, some SiC power devices such as Schottky-barrier diodes (SBDs), metal-oxide-semiconductor field-effect-transistors (MOSFETs), junction FETs (JFETs), and their integrated modules have come onto the market. However, to stably supply them and reduce their cost, further improvements for material characterizations and those for device processing are still necessary. This book abundantly describes recent technologies on manufacturing, processing, characterization, modeling, and so on for SiC devices. In particular, for explanation of technologies, I was always careful to argue physics underlying the technologies as much as possible. If this book could be a little helpful to progress of SiC devices, it will be my unexpected happiness.

Due to the ever-expanding applications of micro/nano-electromechanical systems (NEMS/MEMS) as sensors and actuators, interest in their development has rapidly expanded over the past decade. Encompassing various excitation and readout schemes, the MEMS/NEMS devices transduce physical parameter changes, such as temperature, mass or stress, caused by changes in desired measurands, to electrical signals that can be further processed. Some common examples of NEMS/MEMS sensors include pressure sensors, accelerometers, magnetic field sensors, microphones, radiation sensors, and particulate matter sensors.
