Smart Electronic Textiles

This Review describes the state‐of‐the‐art of wearable electronics (smart textiles). The unique and promising advantages of smart electronic textiles are highlighted by comparing them with the conventional planar counterparts. The main kinds of smart electronic textiles based on different functionalities, namely the generation, storage, and utilization of electricity, are then discussed with an emphasis on the use of functional materials. The remaining challenges are summarized together with important new directions to provide some useful clues for the future development of smart electronic textiles. Working clothes: Electronic textiles are a promising technology that could soon become part of our everyday lives. The three typical functions of wearable electronics—generation, storage, and utilization of electricity—are discussed with a main focus on functional materials.
