Abstract
Wearable electronics are expected to be light, durable, flexible, and
comfortable. Many fibrous, planar and tridimensional structures have
been designed to realize flexible devices that can sustain geometrical
deformations, such as bending, twisting, folding, and stretching
normally at ambient conditions. As a flexible electrode for batteries or
other devices, it possess favorable mechanical strength and large
specific capacity and preserve efficient ionic and electronic
conductivity with a certain shape, structure and function. To fulfill
flexible energy-storage devices, much effort has been devoted to design
of structures and materials with mechanical characteristics. This review
attempts to critically review the state‐of‐arts with respect to
materials, and structural design of devices as well as applications of
the wearable electronic products. Finally, discussion present regarding
to limitations of current materials, fabrication techniques, devices
concerning manufacturability and performance as well as scientific
understanding that must be improved prior to their wide adoption.
