A comprehensive review on the prospects of next-generation wearable electronics for individualized health monitoring, assistive robotics, and communication

Wearable electronics offer a robust and emerging framework for invasive and on-skin electronics that are expected to be long-lasting, lightweight, flexible, and conformable. Critical health data monitoring, such as body temperature, wrist pulse, and blood glucose, can be retrieved and evaluated using next-generation electronic devices fabricated with advanced materials and innovative strategies. Over the past years, these devices have revealed an unprecedented transformation in a variety of other applications, including smart prosthetics, assistive robotics, energy harvesting and storage, display sensors, defense, and so forth. Here, we review the latest advancements in wearable electronics, focusing on three significant areas, including (Ⅰ) personalized health monitoring that enables the recording of several physiological and biochemical signals, (Ⅱ) assistive robotics and prosthetics for limb movements and realizing pain or touch sensations to enable disabled patients, while performing their daily tasks (Ⅲ) information and communication, which includes infrared (IR) sensing and holograms. The categorization of wearable electronics such as mountable, textile-based, implantable, and skin-like electronics are briefly summarized. Furthermore, this review provides in-depth insights into the opportunities and constraints for designing next-generation wearable electronics. As a result, this study includes a thorough introduction, overview, limitations and future prospects of wearable electronics, making it a valuable resource for advancing the development of future electronics.
