Abstract: The present invention is directed towards an article suitable for attachment to facial skin or other surfaces, which comprises microfibrils and continuous microribbons. The article provides good sealing when used on a regular skin, and on a challenge skin surface with facial hair, sweat and acnes. The article also provides good adhesion and sealing on any other rough surfaces, and can be used repeatedly against different surfaces. These dry adhesives can be used for improving sealing of mask respirators, swimming goggles, or for other applications such as medical bandage, working gloves, and protective clothing seal.

Abstract: A solid electrolyte and a piezoelectric material are incorporated into composite shaped articles to provide them with self-healing and adaptive qualities. The piezoelectric constituent converts the mechanical energy concentrated in critical areas into electrical energy which, in turn, guides and drives electrolytic transport of mass within the solid electrolyte towards, and its electrodeposition at critical areas to render self-healing and adaptive effects.

Abstract: Solid electrolyte and at least one of piezoelectric and thermoelectric materials are incorporated into material systems to provide them with self-healing and adaptive qualities. The piezoelectric and thermoelectric constituents convert the mechanical and thermal energy, respectively, concentrated in critical areas into electrical energy which, in turn, guides and drives electrolytic transport of mass within solid electrolyte towards and its electrodeposition at critical areas to render self-healing and adaptive effects. Material systems incorporating the solid electrolyte but not the piezoelectric and thermoelectric constituents are also amenable to healing and adaptive effects through external application of electric potential for electrolytic transport of mass towards and its electrodeposition at critical areas.
