Remarkable progress has been achieved within recent years in developing flexible, wearable, and stretchable (FWS) electronics. These electronics will play an increasingly significant role in thefuture of electronics and will open new product paradigms that conventional semiconductors are not capable of. This is because flexible electronics will allow us to build flexible circuits and devices on a substrate that can be bent, stretched, or folded without losing functionality. This revolutionary change will impact how we interact with the world around us. Future electronic devices will use flexible electronics as part of ambient intelligence and ubiquitous computing for many different applications such as consumer electronics, medical, healthcare, and security devices. Thus,these deviceshave thepotential to create a huge market all over the world. Flexible, Wearable, and Stretchable Electronics, provide a comprehensive technological reviewof the state-of-the-art developments in FWS electronics. This bookoffers the reader a taste of what is possible with FWS electronics and describes how these electronics can provide unique solutions for a wide variety of applications. Furthermore, the book introduces and explains new applications of flexible technology that has opened up the future of FWS electronics.
