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.

- Conductivity,
