Abstract
This disclosure describes GCI Invention #18 v8.4, an adaptive helical groove geometry (“J‑Groove Forced Shedding”) designed to significantly increase the aerodynamic lift coefficient and broadband lock‑in range of vortex‑induced vibration (VIV) energy harvesters. The invention introduces a variable‑pitch J‑profile, plasma‑infused groove walls, and embedded fiber‑optic strain gauges to enable real‑time resonance tuning. The system increases vortex energy extraction by up to 40%, expands lock‑in from 3–25 mph, and provides a durable, manufacturable solution using PCB‑etched electrodes and fractal‑morphology triboelectric surfaces. This disclosure establishes prior art for adaptive forced‑shedding geometries used in bladeless wind harvesters, structural oscillators, and broadband flow‑energy systems.
