Stretchable electronics that offer elastic characteristics
in response to large strain deformation have attracted significant interest for
use in a number of new applications, such as artificial electronic skins
(e-skins), epidermal/biomedical devices, biomimetic lenses, and body sensor
networks (BSNs). Although diverse approaches have been attempted to develop
practical stretchable/wearable electronics and batteries, a challenging problem
is in power supplies, which should have similar elastic properties to achieve
their co-integration with stretchable devices.
