Microsensors – Igor Minin, 294 Pages
This book is planned to publish with an objective to provide a state-of-art reference book in the area of microsensors for engineers, scientists, applied physicists and post-graduate students. Also the aim of the book is the continuous and timely dissemination of new and innovative research and developments in microsensors. This reference book is a collection of 13 chapters characterized in 4 parts: magnetic sensors, chemical, optical microsensors and applications. This book provides an overview of resonant magnetic field microsensors based on MEMS, optical microsensors, the main design and fabrication problems of miniature sensors of physical, chemical and biochemical microsensors, chemical microsensors with ordered nanostructures, surface-enhanced Raman scattering microsensors based on hybrid nanoparticles, etc. Several interesting applications area are also discusses in the book like MEMS gyroscopes for consumer and industrial applications, microsensors for non invasive imaging in experimental biology, a heat flux microsensor for direct measurements in plasma surface interactions and so on.
Microsensors are appropriately categorized as “transducers”, which are defined as devices that convert energy from one form to another. In the case of microsensors, the device typically converts a measured mechanical signal into an electrical signal. The critical physical dimensions of microsensors devices can vary from well below one micron on the lower end of the dimensional spectrum, all the way to several millimeters. Sensors and microsensors are: force and pressure microsensors, position and speed microsensors, acceleration microsensors, chemical microsensors, biosensors and temperature sensors.
The common trends in sensor technology today are: Miniaturization, Integration: sensor with signal processing circuits for linearising sensor output, etc., sensor with builtin actuator for automatic calibration, change of sensitivity etc., and Sensor arrays: onefunction units (to improve reliability), multiple-function units. The main advantages of microsensors, as it is well-known, are: lower manufacturing cost (mass-production, less materials), wider exploitation of IC technology (integration), wider applicability to sensor arrays, lower weight (greater portability). Over the last years, advances in microsensors, computing, physics, chemistry, have enabled new and innovative tests that have allow to design a new devices to improve outcomes.
