Integrated study of triboelectric nanogenerator for ocean wave energy harvestin...
Cátia Rodrigues; Miguel Ramos; R. Esteves; J. Correia; Daniel Clemente; Francisco Gonçalves; Nuno Mathias; Mariany Gomes; João Silva; Cândido DuarteOcean related activities are often supported by offshore equipment with particular power demands. These are usually deployed at remote locations and have limited space, thus small energy harvesting technologies, such as photovoltaic panels or wind turbines, are used to power their instruments. However, the inherent energy sources are intermittent and have lower density and predictability than an alternative sou...
Response of a self-powered offshore floating support structure with an OWC for ...
Nuno Mathias; Rebeca Nunes Marini; Tiago Morais; Pedro Luís; Mário Vaz; Paulo Rosa SantosTo give an effective response to the increasing demand to characterise wind availability and intensity for the installation of future offshore wind farms, SPAR buoy OWCs with LIDAR present a clear benefit, due to their stability, mechanical and operational simplicity and lower cost, when compared to wind measuring towers, serving as an alternative to the latter, mainly for deep water. This paper proposes a comp...
Emerging triboelectric nanogenerators for ocean wave energy harvesting: state o...
Cátia Rodrigues; D. Nunes; D. Clemente; Nuno Mathias; J. M. Correia; Paulo Rosa Santos; Francisco Taveira Pinto; T. Morais; André M. PereiraA triboelectric nanogenerator (TENG) is a new energy harvester that converts small scale mechanical motions into electrical energy by a combination of triboelectrification and electrostatic induction through the periodic contact-separation and/or sliding movement between two tribo-materials with different abilities of gaining or losing electrical charges. This new approach to harvest mechanical energy can produ...
