Body-attachable multifunctional electronic skins for bio-signal monitoring and therapeutic applications

The lack of infrastructure and accessibility in medical treatments has been considered as a global chronic issue since the concept of treatment and prevention was presented. After the COVID-19 pandemic, the medical reaction capability for epidemic outbreak/spread has been spotlighted as a critical issue to the fore worldwide. To reduce the burden on the medical system from the simultaneous disease emergence, the personalized wearable electronic systems have arisen as the next-generation biomedical monitoring/treating equipment for infectious diseases at the initial stage. In particular, electronic skin (e-skin) with its potential for multifunctional extendibility has been enabled to be applied to next-generation long-term healthcare devices with real-time biosignal sensing. Here, we introduce the recent enhancements of various e-skin systems for healthcare applications in terms of material types and device structures, including sensor components, biological signal sensing mechanisms, applicable technological advancements, and medical utilization.
