Building electronics into clothing is a major new concept that opens up a whole array of multi-functional, wearable electro-textiles for sensing/monitoring body functions, delivering communication facilities, data transfer, individual environment control, and so on. Fashion articles will carry key pads for mobile phones and connections for personal music systems; specialist clothing will be able to monitor the vital life signs of new-born babies, record the performance of an athlete's muscles, and call a rescue team to victims of accidents in adverse weather conditions. In this book, a team of international authors discusses the technical materials and processes that will facilitate all of these possibilities.
