ABSTRACT Bioinspired artificial perception systems (APS) are a crucial technical approach for future embodied intelligence, while mimicking perception with low power consumption, high integration, and matched transmission speed is the key element to achieve real‐time high‐efficiency APS. Recently, tribo‐transistors with a simple architecture have provided an innovative solution by directly converting mechanical stimuli into electrical signals, eliminating the need for external tactile sensors and thus improving integration and efficiency. In this review, we extend the discussion to opto–mechano–electric synergistic interactions, highlighting how triboelectric potentials can optically modulate synaptic transistors through field‐controlled charge transfer, exciton dynamics, and band engineering in low‐dimensional materials. We systematically summarize the working principles of triboelectric nanogenerators (TENGs) and tribo‐transistors, with a particular focus on photosensitive materials, optically transparent/active device architectures, and emerging scenarios such as optoelectronic neuromorphic vision systems and light‐triggered multisensory integration. Additionally, the current development prospects and challenges associated with tribo‐transistors APS are critically discussed, including new photonic functionalities such as triboelectric‐modulated photoluminescence and non‐Hermitian photonic sensing. This review aims to provide strategic insights into designing next‐generation APS and to establish a solid foundation for their future deployment in robotics and other advanced intelligent systems.
