DEVICE AND METHOD FOR CONTROLLED ADHESION UPON MOIST SUBSTRATE

摘要

A device for generating an adjustable adhesion force on a wet substrate is described. The device has a main body with an adhesion surface which, in use, arranges itself facing the substrate, at such adhesion surface the main body having a plurality of channels generating a capillary return for water present on the substrate. A delivery and/or reservoir system for silicone oil, providing the latter at the adhesion surface, so that silicone oil arranges itself interposed between the surface itself and the water on the substrate. A static electric field generating system generates a static electric field at the adhesion surface. Such electric field modifies the wettability of silicone oil with respect to the adhesion surface.
