Abstract

La présente invention concerne un dispositif rotatif de conversion d'énergie au moyen d'un liquide et, plus particulièrement, un procédé et un dispositif de conversion d'énergie mécanique en énergie électrique par application d'un phénomène d'électromouillage inverse, qui permet de modifier une surface en contact avec le liquide entre deux électrodes, et d'utiliser la modification de la surface en contact avec le liquide pour générer de l'énergie électrique, de façon à empêcher un blocage de canal ou à rendre inutiles une couche de lubrification ou des électrodes ayant fait l'objet d'une formation de motif compliquée sur un canal, ce qui permet de simplifier le dispositif, d'abaisser le coût de fabrication et d'obtenir un dispositif de conversion d'énergie moins défectueux.
