abstract = {Robust ionic sensing materials that are both
fatigue-resistant and self-healable like human skin are
essential for soft electronics and robotics with extended
service life. However, most existing self-healable
artificial ionic skins produced on the basis of network
reconfiguration suffer from a low fatigue threshold due to
the easy fracture of low-energy amorphous polymer chains
with susceptible crack propagation. Here we engineer a
fatigue-free yet fully healable hybrid ionic skin toughened
by a high-energy, self-healable elastic nanomesh, resembling
the repairable nanofibrous interwoven structure of human
skin. Such a design affords a superhigh fatigue threshold of
2950 J m−2 while maintaining skin-like compliance,
stretchability, and strain-adaptive stiffening response.
Moreover, nanofiber tension-induced moisture breathing of
ionic matrix leads to a record-high strain-sensing gauge
factor of 66.8, far exceeding previous intrinsically
stretchable ionic conductors. This concept creates
opportunities for designing durable ion-conducting materials
that replicate the unparalleled combinatory properties of
natural skins more precisely},
