Patent ID: 7583430

Claim:
A microstructure comprising: a first substrate; a wall microstructure extending from said first substrate and including an end surface disposed opposite said first substrate, said wall microstructure at least partially defining a plurality of microstructural chambers having open ends along said end surface of said wall microstructure; a substance containing one of electrophoretic particles and magnetophoretic particles disposed in one or more of said plurality of microstructural chambers; a second substrate including a first side, said second substrate disposed along said wall microstructure such that said first side is facing said end surface of said wall microstructure; an adhesive disposed along at least a portion of said first side of said second substrate, said adhesive extending between said first side of said second substrate and said end surface of said wall microstructure such that said second substrate is adhesively secured on said wall microstructure and thereby encapsulates said microstructural chambers, said adhesive dispensed from adhesive microcapsules disposed along at least said first side of said second substrate such that a plurality of unruptured adhesive microcapsules remain within said microstructural chambers; and, a first coating disposed between said substance and at least a portion of said plurality of unruptured adhesive microcapsules disposed along said first side of said second substrate, said first coating adapted to minimize irreversible adhesion of said one of electrophoretic particles and magnetophoretic particles to at least said portion of said plurality of unruptured adhesive microcapsules disposed along said first side of said second substrate.
