Abstract
En 中文
A neuromorphic optoelectronic memristor based on a Pt/TiOxNy/NiO/ITO structure is presented to address the limited single-band visible-light response and the lack of biomimetic self-protective functionality in oxide-based optoelectronic memristors. The device exhibits broadband photo response across the entire visible spectrum and light-modulated synaptic plasticity, enabling integrated visual information perception and preprocessing within a single device. The feasibility of the device for target recognition tasks is validated through simulations. In addition, the device emulates key characteristics of biological nociceptors, including a nociceptive threshold, nonadaptive response, relaxation behavior, and sensitization. Nociceptors contribute to embodied intelligence by enabling adaptive responses to harmful environmental stimuli, and the incorporation of such nociceptor-like functionality provides a hardware-level mechanism for early warning and self-protection. This work offers a viable route toward multifunctional neuromorphic systems for biomimetic vision applications.
