Preamble
As a preamble to this book, let us begin immediately by showing our hand. First of all, this book does not attempt to be, is not and will not be an encyclopedia of Wearables – Textiles – smart and connected apparel. There are hundreds of more or less well-made articles on this subject on the Net, making grand theoretical claims of the future and of giant markets to come of all varieties, of outrageous and fabulous commercial figures, etc. From our side, since we are not amateurs of unproductive redundancies, we concentrated solely on subjects, for which we found fewer articles by far, which is to say the grounded side, the daily side of this domain, to concretely and technically process the broad field of Applications and Designs of all sorts, in order to provide you with a guide, and to not forget anything such as to avoid the false turns, which can occur during the design and realization of Wearables and Textiles – smart and secured and connected apparel because this is the aim and the hidden core of this book. Talking, making pretty speeches, fancy conferences and great demonstrations are all fine (how many times have we seen and heard that), but concretely, physically completing a Wearable or connected clothing with a commercial objective, and managing to sell it in bulk at a reasoned and reasonable price is even better, otherwise, we might as well do nothing, with no inconsiderate fuss! As such, at the end of this book we will describe the steps to follow and respect for your project in order to avoid the usual pitfalls and to ease the passage from the virtual world to the real, blatantly concrete world, and we suggest a reasonable path of wisdom, based on a realistic awareness of the world of technical, economic, ergonomic norms, etc., and not “free trims tomorrow”! So there is the admitted aim of this book, and it is largely sufficient as it is!
