Kurzinhalt: This book provides a unique guide to the fundamental principles, advantages and disadvantages of modelling, measurement devices and measurement error. Presenting both the latest developments and the classical solutions in the field of electrical measurement, this book will be an invaluable reference source for senior students in electrical, electronic and mechanical engineering, together with practising engineers and researchers.
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.

This book, which is divided into twelve chapters, aims to present the reader with an introduction to the electrical characterization of materials, specifically solid materials. In this book, the reader will find both theoretical and experimental concepts of some methods that can be used to know and understand physically the electrical response of different materials. In this project, a theoretical scan is made of several experimental techniques that characterize materials at the level of dc and ac conductivity. In ac conductivity, several approaches are presented from techniques in the low frequency regime (i.e., in the range of the radio frequencies) up to the regime of higher frequencies (i.e., in the range of microwaves). An introductory analysis of dielectric relaxation phenomena through the impedance spectroscopy as well as the phenomena of thermally stimulated polarization and depolarization are discussed. In preparing this book, each contributor was asked to present in the end of each chapter a small, but specific case study, with the purpose of facilitating the transposition of the methods and theories presented for a real case. This approach is a valuable part of this book, which includes analyses of different types of materials with structures, forms and electrical responses, from glasses, ceramics, and biomaterials to photoactive materials with potential use in photovoltaic cells.
In this modern scientific world a thorough understanding of complex measurements and instruments is the need of the hour. This book provides a comprehensive coverage of the concepts and principles of measurements and instrumentation, and brings into focus the recent and significant developments in this field.
