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 towards 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 use of artificial intelligence (AI) in wearable technology. In this study, an emphasis has been laid towards the applications of AI in wearable devices along with brief insight into advantages, and limitations of AI and ML in the field of medicine.
