Access to electricity in rural Peru remains uneven, while conventional renewables face cost and siting constraints. This study designs and evaluates a piezoelectric plate prototype that converts vehicular loads into electrical output and links laboratory results to a traffic-based simulation. Press tests recorded voltage spikes up to 73.5 V, and the Arena model—parameterized with one hour of counts (5,861 vehicles; 120 replications)—yielded an average of 19.7333 V per axle and a total of 232,020 V. Converting to a stable metric, the prototype produced 32.24 watt-hours. The contribution is a bench-to-traffic translation that quantifies energy under realistic load patterns and clarifies deployment conditions. Findings indicate feasibility for low-demand devices with appropriate conditioning and storage, informing siting along high-throughput corridors and guiding material and measurement improvements. Academically, the work connects PEH testing to traffic realism; socioeconomically, it outlines a pathway for micro-supply near underserved areas. Further pilots and durability studies are encouraged.
