Here, we propose versatile ionic conductors for high-performance, deformable and functional ionic sensory platforms by tailoring the mechanical properties of ionic conductors. For instance, porous ion gels simply fabricated by sugar cube can be effectively deformed by closing pores even with small pressure, a broad variation in the contact area of the porous gel and electrodes is induced, leading to a dramatic difference in electrical double layer (EDL) capacitance. More interestingly, the functionality of the porous ion gel is extended to include electrochemiluminescence (ECL), resulting in the production of emissive ECL ionoskins. Furthermore, the deformability of ionic conductors is tailored by using binary polymer blends as the co-gelators. To reduce the chain entanglement of polymer gelators and induce effective dissipation of applied stresses, flexible low Tg polymer is doped into the ionic conductor. The optimized ternary blend ionic conductors exhibit outstanding stretchability, mechanical elasticity and durability.
