Robust carbon-doped black phosphorus multi-perception memristor for a hazardous information detection system

The perception of hazardous information is a crucial factor in ensuring safety in production. In recent years, multi-mode sensing has been proven to be an effective approach for developing efficient perception systems. However, these systems still rely on various combinations of single-function sensors within traditional von Neumann architecture, which increases the system's overall complexity. In this study, carbon-doped black phosphorus (C–BP)-based multi-perception memristors were successfully developed for hazardous information perception. The C–BP multi-perception memristor exhibits remarkable stability and high surface activity due to the coupling and synergistic effects of C doping. Its high surface activity enables the reliable perception of hazardous visual (ultraviolet light) and olfactory (ethanol, acetone, and human expirations) information in an open environment. Consequently, a hazardous detection system based on the C–BP multi-perception memristor was simulated. The results indicate that the developed system outperforms traditional detection systems with an enhanced performance rate (97.6% vs. 90.5%) in perceiving hazardous information. This work may provide new insights into developing enhanced-performance hazardous information perception systems.
