Floating Platform Geometry as a Frequency‐Selective Mechanism for Triboelectric Wave Energy Harvesting

SmartSys, Volume 2, Issue 3, September 2026.
ABSTRACT Ocean wave energy has enormous potential for sustainable power generation but conventional technologies often face challenges in efficiency, durability, and adaptability to specific sites. Triboelectric nanogenerators (TENGs) are able to convert irregular and low frequency water motion into electrical energy, but their performance depends on ...

Analyzing the Near-Field Effects and the Power Production of an Array of Heaving Cylindrical WECs and OSWECs Using a Coupled Hydrodynamic-PTO Model

Energies, 2018
The Power Take-Off (PTO) system is the key component of a Wave Energy Converter (WEC) that distinguishes it from a simple floating body because the uptake of the energy by the PTO system modifies the wave field surrounding the WEC.
