Abstract

Harnessing ocean waves for power demands robust converters that overcome the narrow bandwidth and instability of traditional resonant devices. Here, we present a gimbaled pendulum wave energy converter (GP-WEC) that exploits nonlinear chaos for broadband energy harvesting. Through parametric optimization and bifurcation analysis, we demonstrate a peak capture width ratio of 38.4 % at an off-resonant wave period (1.2 s), with high efficiency sustained across a broad spectrum. Crucially, the rotary pendulum decouples from the chaotic motion of its tray, rectifying irregular excitations into stable, high-amplitude rotation, as validated by wave-flume experiments. This mechanism ensures consistent power output even under high-entropy waves, establishing the GP-WEC as a promising platform for sustainable offshore power.
