Abstract Ionogels consist of polymers and ions have emerged as promising application in flexible electronic devices. However, challenges remain achieving the mechanical properties low‐temperature tolerance ionogels. Here, a cellulose ionogel is reported by triggering mechano‐induced alignment molecular chains incorporating Ca 2+ complexation interactions. This presents outstanding ionic conductivity, featuring tensile strength 6.84 MPa, an elastic modulus surpassing 100 conductivity 31.7 mS·cm −1 . Furthermore, networks provide with remarkable freezing resistance, allowing it to maintain flexibility even at temperatures low −196 °C, while assembled skin displays reliable sensing performance. The combination robust strength, high biocompatibility, extreme temperature underscores potential applications this ionogel, ensuring stable operation devices highly challenging environments.
