Ionogels are increasingly used in flexible strain sensors, but it is still challenging to incorporate multifunctional properties such as flexibility, self-healing, adhesion, temperature resistance, and electrical conductivity. Herein, a facile rapid one-step photoinitiated polymerization strategy employed prepare ionogels by filling hydrophobic conductive ionic liquid into flexible, fluoropolymer matrix. Thanks the presence of abundant noncovalent interactions (hydrogen-bonding ion-dipole interactions), exhibit high transparency, excellent mechanical properties, self-healing ability, adhesion. Moreover, rich C-F bonds matrix can eliminate interference water molecules, resulting environmental tolerance low waterproofness, anticorrosion. Furthermore, ionogel-based wearable sensor sensitively detect differentiate human movements subtle muscle serve Morse code signal transmitter for information transmission. The presented work provides an effective method develop versatile devices ionotronics.
