Abstract Ionic conductive hydrogels have emerged as an excellent option for constructing dielectric layers of interfacial iontronic sensors. Among these, gradient ionic hydrogels, due to the intrinsic elastic modulus, can achieve a wide range pressure responses.

Multisensory integration enables the simultaneous perception of multiple environmental stimuli while minimizing size and energy consumption. However, conventional multifunctional in flexible electronics typically requires large-scale horizontal sensing arrays (such as printed circuit boards), posing decoupling complexities, tensile strain limitation, spatial constraints. Herein, a fully multimodal system (FMSS) is developed by coupling biomimetic stretchable conductive films (BSCFs) strain-insensitive communication interfaces using vertical stacking strategy. The FMSS achieves without additional adhesives, it can incorporate individual layers interconnects any essential constraint on their deformations. Accordingly, temperature pressure are precisely decoupled simultaneously, stress be accurately discerned different directions. This strategy expected to offer new approach significantly streamline design fabrication systems enhance capabilities.
