Ionic liquid-based solid polymer electrolytes, commonly referred to as ionogels, have garnered significant attention in research due to their exceptional attributes, encompassing thermal and electrochemical stability, mechanical resilience, high stretchability, non-volatility, and elevated ionic conductivity. To enhance the durability and reliability of stretchable strain sensors, it is crucial for the sensing elements to endure a wide spectrum of mechanical fluctuations while maintaining adequate mechanical strength. To achieve this, we adopted a double networks (DN) approach, by employing phyically and chemically cross-linkable polymer matrics in ionic liquids. The physically crosslinked network in the gel could easily be controled viscosity for 3D printing. In terms of sensing capability, improving the sensitivity of stretchable sensors is essential for accurate conversion of mechanical deformation. Simultaneously, the chemically crosslinked network in the DN ionogel provided strong adhesion between a substrate and the ionogel through the incorporating chemical bonds. To heighten the sensitivity of the strain sensor, the ionogel was engineered with multi-angle zigzag pattern by utilizing 3D printing. We introduced a patterned the gaps (zigs) in the sensing element that widen as the sensor stretches, and close as it contracts, resulting in a substantial variation in the relative resistance (ΔR/R0) upon stretching and resulting in a remarkable gauge factor (GF) of 116.90, which is record-high. Furthermore, by incorporating zigzag patterns at various angles, the gap can sequentially expand in response to strain deformation, facilitating a linear response across a broad sensing range of 100%. The resulting stretchable strain sensors can precisely detect various motions and convert them into electrical signals.
