The device which controls the flow of electrons is called electronic device. These devices are the main building blocks of electronic circuits. Engineers design and test circuits that use the electromagnetic properties of electrical components such as resistors, capacitors, inductors, diodes and transistors to achieve a particular functionality. The tuner circuit, which allows the user of a radio to filter out all but a single station, is just one example of such a circuit. Integrated circuits and other electrical components can then be assembled on printed circuit boards to form more complicated circuits. Today, printed circuit boards are found in most electronic devices including televisions, computers and audio players.

This book entitled “Electronic Devices And Circuits” contains a collection of latest research developments on the printed electronics from the material-related various processes to the interdisciplinary device applications by a selected group of authors including promising novices to experts in the field. The intent of this book is to provide readers the backgrounds and trends of the electronics devices, including processes, and specific areas of applications. Currently, the research on the electronics devices is confronted with many issues including material and printing process issues. In addition, for the specific applications with low‐cost and high‐volume manufacturing, the solutions for the issues may be different depending on the applications.

Therefore, this book can allow readers to provide the fundamentals of the printed electronics in process or device levels as well as the circuit level implementation scheme for applications. Furthermore, this book can provide a clue for the readers on how to solve their current issues for their specific applications. In telecommunication, entertainment devices, computational techniques, clean energy harvesting, medical instrumentation, materials and device characterization and scores of other areas of R&D the science of electronics get coupled by fine technology advances to make incredibly large strides.

This book will be interested for graduate students, engineers, and researchers in the area of the electronics. Some chapters’ focus on the fundamental concepts of the proposed topics and some chapters portray the advanced concept of the specific area of the electronics.
