Recently there has been enormous interest in the field of low-cost circuit fabrication. Producing electronics at costs far below those currently available on the market requires adoption of new materials and processing techniques. This book takes a system-level approach to design by first analyzing the minimum performance requirements for each application then showing how new alternative approaches can meet these require-ments at extremely low cost. Antennas for radio-frequency identi-fication (RFID) tags are analyzed in detail, as are active-matrix display backplanes. Ink-jet printing techniques are shown to be extremely useful, especially when combined with aqueous chemical deposition methods. Solutions to the low-cost challenge takes a multidisciplinary approach, incorporating several different fields, and thus this book will benefit electrical engineers, chemists, and material scientists who have an interest in applying their expertise towards a new and exciting field.
