Ionogels have enabled flexible electronic devices for wide-ranging innovative applications in wearable electronics, soft robotics, and intelligent systems. Ionogels for flexible electronics need to essentially tolerate stress, temperature, humidity, and solvents that may cause their electrical conductivity, structural stability, processing compatibility and sensibility failure. Herein, we developed a novel in-situ photopolymerization protocol to fabricate intrinsically conductive, self-gated ionogels via ion-restriction dual effects. Highly sensitive and intelligent safety sensors with tunable stretchability, robust chemical stability, favorable printability, and complete recyclability, are programmed from defined microneedle arrays printed by the intrinsically conductive ionogel. Ultrahigh elasticity (~ 794% elongation), high compression tolerance (~ 90% deformation), improved mechanical strength (tensile and compressive strength of ~ 2.0 MPa and ~ 16.3 MPa, respectively) and remarkable transparency (> 91.1% transmittance), as well as high-temperature sensitivity (- 2.07% °C-1) and a wide working range (- 40 to 200 °C) can be achieved. In particular, the intrinsic sensing mechanisms of ion-restriction dual effects are unlocked based on DFT calculations and MD simulations, and operando temperature-dependent FTIR, and Raman technologies. Moreover, the real-time intelligent monitoring systems toward physical signals and precise temperature based on the microneedle array-structures sensors are also presented and demonstrate great potential applications for extreme environments, e.g., fire, deep-sea or aerospace.
