Electronic skin is the flexible and
wearable electronic system
mimicking the functions and mechanical properties of the biological
skin, which received increasing interest in recent years. Although
efforts have been made to implement skin-like electronics in applications
from everyday healthcare to advanced robotics, tremendous challenges
in terms of immatual material selection and unbalanced device performances
hinder its commercialization process. This Perspective covers the
typical design difficulties of electronic skins, including effect
of deformation on electrical properties, challenges in measuring precision
and stability, integrating multisensories cooperatively, and manufacturing
skills and process for large-scale production. In each section, works
committed to solving such challenges from aspects of material modification,
device preparation, and system design, together with potential research
directions are highlighted.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
