In this work, we propose dynamically switchable dual-mode wearable sensory platforms based on electrical-ionic bimodal conductors that integrate both electrical and ionic conductive characteristics within a simple bilayer structure. The conductor design incorporates highly conductive, crack-forming electrical channel and elastic ionic channel. Each conduction layer serves as the primary sensing channel, depending on the strain range. The electrical channel demonstrates superior performance in detecting low strains, leveraging dramatic resistance changes caused by the disruption of the electrical conducting network under strains. In contrast, the ionic channel adjusts its resistance in response to geometric deformation upon stretching, enabling the detection across a broad strain range. The optimized sensory platform exhibits outstanding performance metrics, including high sensitivity, substantial deformability, and remarkable durability
