Nonvolatile ionogels have recently emerged as promising soft electrolyte materials for use in flexible electronics. However, it remains challenging to fabricate highly robust and stable transparent ionogels. Here, high-performance ionogels with excellent transparency, mechanical robustness, and ultrahigh stability are designed by virtue of hydrogen bonding between poly(ethyl acrylate)-based elastomers and room-temperature ionic liquids (ILs). Through rationally tuning the chemical structures of ILs and thus achieving good compatibility of ILs with elastomers, the transparent hydrophobic ionogels exhibit super-strong mechanical properties (favorable elasticity of 15-484 kPa, ultrahigh stretchability of more than 5000%, and record-high fracture toughness of up to 4.7 kJ m(-2)) and high stability (high thermal stability, high voltage stability, air stability, humidity resistance, strong self-adhesion, and non-corrosive stability). In particular, it is demonstrated that a skin-like sensor fabricated using the ionogel directly not only exhibits outstanding durability (10 000 cycles at 100% strain), but is also capable of operation under harsh environmental conditions, including high vacuum, high/low temperatures, and high humidity. It is believed that this work provides new prospects for sophisticated wearable optoelectronic devices.
