Extracting information on a system is required to understand its state, to describe its behavior and to predict any early damage in order to be able to undertake the necessary corrective actions. The essential mechanism for data acquisition is the physical sensor, which can be electronic, chemical, biological, mechanical, acoustic, etc. For some years, the sensor environment has been changing. The sensor has become a central part of a more complex process, with sensors operating as a team, communicating, making decisions and being able to diagnose the state of the system being monitored. The instrumentation chain, the processing chain and the decision-making process can all be seen as software sensors.
This book focuses on the processing chain that needs to be set up in order to extract relevant information on various systems. The design of new microsensors is particularly highlighted and various applications are presented. It presents recent progress in instrumentation, microsystem design, giving an insight into the modification of the sensor itself but also its environment. Presentations are illustrated with various applications, which show how a processing chain is organized from the data acquired by a specific sensor to provide relevant information leading to the analysis of the driver behavior, the characterization of failure in industrial processes, the selective recognition of antigens/antibodies, etc.
