Stretch-release adhesive articles with tunable mechanical properties are provided. The articles include a stretchable carrier extending along a first direction and including a first major surface and a second major surface opposite the first major surface. At least one of the first and second major surfaces of the stretchable carrier is a stretch-releasable adhesive surface, and the stretchable carrier includes a pattern of slits distributed thereon and configured to deform upon a stretch on the stretchable carrier to elongate the stretchable carrier. L'invention concerne des articles adhésifs détachables par étirement présentant des propriétés mécaniques ajustables. Les articles comprennent un support étirable s'étendant dans une première direction et présentant une première surface principale et une seconde surface principale opposée à la première surface principale. Au moins l'une desdites première et seconde surfaces du support étirable est une surface adhésive détachable par étirement et ledit support étirable, sur lequel est réparti un motif de fentes, est conçu pour se déformer lorsque ledit support étirable est soumis à un étirement afin d'être allongé.
