Sensors and actuators are now part of our everyday life and appear in many appliances, such as cars, vending machines and washing machines. MEMS (Micro Electro Mechanical Systems) are micro systems consisting of micro mechanical sensors, actuators and micro electronic circuits. A variety of MEMS devices have been developed and many mass produced, but the information on these is widely dispersed in the literature. This book presents the analysis and design principles of MEMS devices. The information is comprehensive, focusing on microdynamics, such as the mechanics of beam and diaphragm structures, air damping and its effect on the motion of mechanical structures. Using practical examples, the author examines problems associated with analysis and design, and solutions are included at the back of the book. The ideal advanced level textbook for graduates, Analysis and Design Principles of MEMS Devices is a suitable source of reference for researchers and engineers in the field.* Presents the analysis and design principles of MEMS devices more systematically than ever before.* Includes the theories essential for the analysis and design of MEMS includes the dynamics of micro mechanical structures* A problem section is included at the end of each chapter with answers provided at the end of the book.
Seven years have passed since the publication of the previous edition of this book. During that time, sensor technologies have made a remarkable leap forward. The sensitivity of the sensors became higher, the dimensions became smaller, the sel- tivity became better, and the prices became lower. What have not changed are the fundamental principles of the sensor design. They are still governed by the laws of Nature. Arguably one of the greatest geniuses who ever lived, Leonardo Da Vinci, had his own peculiar way of praying. He was saying, “Oh Lord, thanks for Thou do not violate your own laws. ” It is comforting indeed that the laws of Nature do not change as time goes by; it is just our appreciation of them that is being re?ned. Thus, this new edition examines the same good old laws of Nature that are employed in the designs of various sensors. This has not changed much since the previous edition. Yet, the sections that describe the practical designs are revised substantially. Recent ideas and developments have been added, and less important and nonessential designs were dropped. Probably the most dramatic recent progress in the sensor technologies relates to wide use of MEMS and MEOMS (micro-electro-mechanical systems and micro-electro-opto-mechanical systems). These are examined in this new edition with greater detail. This book is about devices commonly called sensors. The invention of a - croprocessor has brought highly sophisticated instruments into our everyday lives.
Advances in materials science and engineering have paved the way for the development of new and more capable sensors. Drawing upon case studies from manufacturing and structural monitoring and involving chemical and long wave-length infrared sensors, this book suggests an approach that frames the relevant technical issues in such a way as to expedite the consideration of new and novel sensor materials. It enables a multidisciplinary approach for identifying opportunities and making realistic assessments of technical risk and could be used to guide relevant research and development in sensor technologies.
Sensors for measuring and detecting chemical and biological substances are comprehensively used and are, for the most part, unobtrusive. They can help monitor our health through alerting us to chemical or biological changes in our bodies, our environment through checking air quality or pollution levels and they can contribute towards a more sustainable future. Polymer-based sensors are the subject of much attention due to their ability to collect molecules on their flexible sensory surfaces. However, most petroleum-based polymers are not renewable, leading to problems of waste-disposal. By using renewable materials, such as paper, cotton or starch, these problems can be overcome. This book reviews the current state-of-play in renewable-material-based chemical sensors and biosensors, and suggests applications in industry, environment and biomedicine.
The book gives an insight into today's operational measurement technology including analysis technology, without claiming to be complete. For the student, the book is an introduction in addition to the relevant textbooks and manuals. It gives the engineer in the profession a quick overview of measurement methods and instruments not familiar to him. In this book not only the components of measurement technology are presented transparently, but also the analog components that are necessary for the construction of measurement and control systems. The theoretical basics and the measuring methods are as much a part of the book as the description of systems, devices and measuring equipment. By indicating measuring ranges and error limits, additional reference points for the application are given, whereby the values mentioned are to be regarded as minimum values due to the constant technical development. This book is a translation of the original German 1st edition Messelektronik und Sensoren by Herbert Bernstein, published by Springer Fachmedien Wiesbaden GmbH, part of Springer Nature in 2014. The translation was done with the help of artificial intelligence (machine translation by the service DeepL.com). A subsequent human revision was done primarily in terms of content, so that the book will read stylistically differently from a conventional translation. Springer Nature works continuously to further the development of tools for the production of books and on the related technologies to support the authors.
Modern air and space craft demand a huge variety of sensing elements for detecting and controlling their behavior and operation. These sensors often differ significantly from those designed for applications in automobile, ship, railway, and other forms of transportation, and those used in industrial, chemical, medical, and other areas. This book offers insight into an appropriate selection of these sensors and describes their principles of operation, design, and achievable performance along with particulars of their construction. Drawn from the activities of the International Federation of Automatic Control (IFAC), especially its Aerospace Technical Committee, the book provides details on the majority of sensors for aircraft and many for spacecraft, satellites, and space probes. It is written by an international team of twelve authors representing four countries from Eastern and Western Europe and North America, all with considerable experience in aerospace sensor and systems design. Highlights include: • coverage of aerospace vehicle classification, specific design criteria, and the requirements of onboard systems and sensors; • reviews of airborne flight parameter sensors, weather sensors and collision avoidance devices; • discussions on the important role of inertial navigation systems (INS) and separate gyroscopic sensors for aerospace vehicle navigation and motion control; • descriptions of engine parameter information collection systems, including fuel quantity and consumption sensors, pressure pick-ups, tachometers, vibration control, and temperature sensors; and • descriptions and examples of sensor integration.
