Abstract
The present invention relates to a carrier for adhesive, with the carrier being configured to be attached to a surface having a topology, in particular a time variable topology, such as a part of a human or animal body. The invention further relates to a use of the carrier, to a method of activating a carrier and to a method of making a carrier.
Claims21
A carrier for adhesive, with the carrier being configured to be attached to a surface, the carrier comprising:
- a backing substrate, wherein the backing substrate is an interface to a payload;
- a patterned surface having islands present at the surface;
- wherein at least one of the islands and the backing substrate is made from a compliant material,
- wherein at least a part of a free surface of the islands is coated with an ink comprising curable material,
- wherein the curable material is a material that provides a cross-linking or adhesion to the material of the islands, with the curable material being the same type of material as the islands or the same material as the islands in combination with one or more materials selected from the group of members consisting of thermally crosslinkable material, photocrosslinkable material, moisture crosslinkable material, catalytically crosslinkable material, or redox reaction crosslinkable material,
- wherein the ink, after being coated in an uncured state on the free surface of the islands and brought into contact with a further object, and thereafter completely cured, is selected to bond the islands of the carrier to the further object, wherein the ink is selected to form a connection between the payload and the further object, and wherein the payload is configured to determine properties of the object and/or to exert a function on the object, and wherein the ink is tailored to the respective property and/or function for enhancing the transmission of the respective property and/or function to and/or from the payload.

A method of activating a carrier for bonding to an object, the carrier comprising:
- a backing substrate, wherein the backing substrate is an interface to a payload;
- a patterned surface having islands present at the surface;
- wherein at least one of the islands and the backing substrate is made from a compliant material, with the method comprising the steps of:
- at least partly immersing the islands of the carrier into an ink reservoir containing uncured ink, the uncured ink being the same type of material as the islands or the same material as the islands in combination with one or more materials selected from the group of members consisting of thermally crosslinkable material, photocrosslinkable material, moisture crosslinkable material, catalytically crosslinkable material, or redox reaction crosslinkable material, placing the islands of the carrier comprising the uncured ink present thereon onto an object;
- and
- curing the uncured ink to adhere or form a bond between the carrier and the object to form a connection between the payload and the object via the cured ink, wherein the payload is configured to determine properties of the object and/or to exert a function on the object, and wherein the cured ink is tailored to the respective property and/or function for enhancing the transmission of the respective property and/or function to and/or from the payload.
