Human skin can function steadily regardless of surrounding circumstances (dry or wet),while it is still a challenge for artificial ionic skins,which tend to release solvents in dry air and leach electrolytes in wetted state.Herein,a series of hierarchically crosslinked ionogels containing hydrophobic ionic liquids (ILs) is fabricated by combining a crystalline fluorinated copolymer with hydrophobic ILs.With a reasonable combination of nonvolatility,transparency,stretchablility,and sensitivity,such ionogels can work as reliable sensors for real-time monitoring human motions and operate steadily in complex environments as human skin does,which can contribute to the development of durable sensing devices with a simple design.
