Abstract:
This protocol outlines the fabrication and application of a starfish-inspired magnetoelastic generator (MEG) array for ocean wave energy harvesting and autonomous hydrogen (H2) production. We detail the procedures for device design, frame and MEG fabrication, magneto-mechanical coupling (MC) layer characterization, and array assembly. We also describe procedures for evaluating electrical performance, converting AC to DC output, and enabling MEG-driven on-site water-splitting, offering a comprehensive strategy for sustainable ocean wave energy harvesting and direct H2 fuel generation. For complete details on the use and execution of this protocol, please refer to Ock et al.1.

Magnetic Force Between Two Parallel Currents
The force exerted by the magnetic field due to the first conductor over a finite length of the second conductor is given as the product of the current in the second conductor and the vector product of the length vector along the current element and the field due to the first conductor. According to the...
