Triboelectric nanogenerators (TENGs) are in the spotlight for their inexpensive and non\u2010toxic manufacturing, allied with their excellence in harvesting low frequency vibrations. Ocean waves are a prime example of energy source in this regime, and their successful harvesting with TENGs has been widely demonstrated. However, the influence of wave characteristics on the power output of these devices has so far been overlooked. Here, the existence of a moving element that acts upon the nanogenerators is explored both with multiphysics simulations and an extensive experimental characterization under different operating conditions. It is\u00a0shown how different sea states modulate the moving body velocity, and how the generator can be optimized to harvest waves with specific characteristics. In parallel, it is\u00a0demonstrated that the power output is proportional to the contacting triboelectric layers velocity. Optimizing the dynamics of the moving body provides an efficient path to intentionally tune the contacting triboelectric layers velocity, and therefore improve the output of TENGs and their suitability to harvest specific sea\u00a0states.<\/jats:p>","DOI":"10.1002\/aenm.202302627","type":"journal-article","created":{"date-parts":[[2023,11,24]],"date-time":"2023-11-24T20:09:46Z","timestamp":1700856586000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":35,"title":["Sea State Adaptation Enhances Power Output of Triboelectric Nanogenerators for Tailored Ocean Wave Energy Harvesting"],"prefix":"10.1002","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3019-0744","authenticated-orcid":false,"given":"Isabel","family":"Gon\u00e7alves","sequence":"first","affiliation":[{"name":"IFIMUP and Department of Physics and Astronomy Faculty of Sciences University of Porto Rua do Campo Alegre 687 4169\u2010007 Porto Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9558-0954","authenticated-orcid":false,"given":"C\u00e1tia","family":"Rodrigues","sequence":"additional","affiliation":[{"name":"IFIMUP and Department of Physics and Astronomy Faculty of Sciences University of Porto Rua do Campo Alegre 687 4169\u2010007 Porto Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0494-3009","authenticated-orcid":false,"given":"Jo\u00e3o","family":"Ventura","sequence":"additional","affiliation":[{"name":"IFIMUP and Department of Physics and Astronomy Faculty of Sciences University of Porto Rua do Campo Alegre 687 4169\u2010007 Porto Portugal"}]}],"member":"311","published-online":{"date-parts":[[2023,11,23]]},"reference":[{"key":"e_1_2_9_1_1","unstructured":"World Meteorological Organization State of the global climate 2022 Tech. rep.
