Trends in Graphene-Based E-Skin and Artificial Intelligence for Biomedical Applications—A Review

Electronic skin (e-skin) mimics human skin and is an indispensable part of wearable technology with widespread applications ranging from robotics to health care. Designing and fabricating e-skins equipped with multifunctionality is the focus of current research that amalgamates materials with a variety of structures and unique properties. Several attempts toward various mechanisms and materials that make e-skin flexible, stretchable, and sensitive have been reported. At the material level, graphene is the most suitable material for e-skin owing to its excellent electronic, electrical, and mechanical properties. Although remarkable progress has been made in this field over the years, fabricating multifunctional smart e-skin is still a challenge. This perspective article explores the recent advances in e-skin through graphene as a material example and the use of artificial intelligence (AI) in wearable technology. In this study, an emphasis has been laid on the applications of AI in wearable devices along with a brief insight into the advantages, and limitations of AI and ML in the field of medicine.
