The escalating global challenges of water scarcity and energy deficit in montane fog-prone regions have spurred biomimetic innovations in fog collection systems. This study presents an integrated fog collection system (IFCS) inspired by hyperbolic androecium architecture in Hypericum flowers achieving innovative synergy between bio-inspired droplet capture and triboelectric wind energy harvesting. The system uses copper needles to mimic “stamens” for efficient droplet capture and integrates ultraslippery windmill blades (US-WBs) to achieve synergistic effects in rapid droplet transport and wind power generation. This study conducts a systematic investigation into the wettability and spatial configuration of copper-needle arrays, coupled with geometry optimization of US-WBs guided by Betz limit theory. This dual approach achieves synergistic integration of droplet capture-transport dynamics within the IFCS framework, while concurrently enhancing wind energy harvesting efficiency. Ultimately, the IFCS achieves efficient fog collection (0.249 g∙cm−2∙min−1) and stable output voltage (0.513 V). This dual-function platform establishes a novel paradigm for sustainable development in arid zones, addressing both potable water scarcity and decentralized energy needs through biomimetic engineering.
