Abstract The rapid advances in Artificial Intelligence and Internet of Things technologies have fueled a growing demand for high‐performance, multimodal neuromorphic sensory systems. However, existing artificial sensory platforms still face challenges in terms of multimodal capabilities, device compatibility, and energy efficiency. Here, a self‐powered bionic auditory‐tactile bimodal perceptual platform (SBAT‐BPP) is proposed by integrating triboelectric nanogenerators (TENG) and chitosan‐gated oxide ionotronic neuromorphic transistors (CINT). It can achieve efficient bimodal perception of auditory and tactile signals. The TENG‐based artificial receptors demonstrate exceptional acoustic sensitivity of ≈1.65 V dB −1 and pressure sensitivity of ≈63 mV N −1 , surpassing conventional unimodal sensors, providing critical technical support for multisensory intelligent perception. While the CINT with synaptic plasticities achieves unified sensing‐memory‐processing functionality. Benefiting from the self‐power, simple architecture, and multimodal perceptual capabilities, the SBAT‐BPP shows broad application prospects in the fields of hearing health monitoring, dynamic sound localization and trajectory recognition, and haptic human‐machine interaction, offering an innovative solution for the development of an intelligent perceptual system and human‐machine interaction
