This is a thought-provoking theme, covering a broad range of aspects of issues, from basic concepts that composes the known "4th industrial revolution" (artificial intelligence, cloud computing, internet of things, big data, robotics and computer systems), all of which has been used in different healthcare sectors, to more recent technologies applied to healthcare, such as smartphone applications, remote consulting, augmented reality, gamification and brain-machine interactions. All chapters cover detailed explanations of all these technologies and how are the possible uses and applications in healthcare in different contexts, with a multidisciplinary approach, including the vision of technology, health and social sciences researchers. The great difference of this book is the coverage of updated topics, with the most advanced knowledge of all the technologies described in each chapter, covering virtually every innovation in healthcare, and the multidisciplinary approach, making the book accessible to researchers from different fields of knowledge.
