This book offers a comprehensive and cutting-edge exploration of intelligent wearables, tracing their evolution from conceptual prototypes to intelligent systems that are reshaping personalized healthcare and human-machine interaction. It systematically addresses the fundamental question of how wearable devices can transition from passive data collectors to active, adaptive platforms capable of real-time health monitoring, disease prediction, and even therapeutic intervention. By integrating insights from materials science, flexible electronics, microsystems engineering, and artificial intelligence, the book provides a holistic view of the technologies enabling this transformation.

Structured into five parts across twenty chapters, the content begins with the foundational concepts and historical development of intelligent wearables, establishing a clear framework for understanding their classification and core principles. The heart of the book lies in its detailed examination of the key components that make wearables intelligent: advanced materials (including inorganic, organic, biomaterials, and novel composites), multi-signal sensors, energy harvesting devices, actuators, and data processing modules. It delves into the working principles, current challenges, and recent breakthroughs in each area, highlighting how triboelectric nanogenerators, photovoltaic cells, and flexible sensors are paving the way for battery-free, self-powered systems. The integration of artificial intelligence and the Internet of Things is explored in depth, demonstrating how machine learning and cloud computing enable wearables to perform adaptive calibration, personalized modeling, and emotion recognition from multimodal signals. Critical issues such as data security, privacy, and the ethical use of sensitive health information are also addressed, with discussions on encryption, privacy computing, and blockchain.

Beyond technology, the book maps out the vast landscape of wearable applications, spanning health monitoring, tissue engineering, drug delivery, neural rehabilitation, smart clothing, and sports performance analysis. It confronts the key challenges hindering widespread adoption, including industry standardization, long-term reliability, and user acceptance, while offering insights into future directions. By synthesizing theoretical foundations with practical case studies, this volume serves as both a reference for seasoned researchers and a roadmap for innovators entering the field. It is an indispensable resource for materials scientists, electrical engineers, biomedical researchers, AI specialists, industry professionals, and graduate students seeking to understand and contribute to the rapidly evolving world of intelligent wearables.
