Abstract
A thermo-reversible dry adhesive, having shape memory polymer characteristics, introduces one or more particles of micro- or nano-particles to at least one layer of the at least one layer of shape memory polymer. These particles may be remotely activated to induct heat sufficient to transform the dry adhesive material from its temporary shape to its permanent shape in the absence of load, which allows the dry adhesive to be reversibly coupled to one or more substrates, wherein the degree of adhesion is greater when the dry adhesive is in the temporary shape than in the permanent shape.
