Title:
MINIATURE CILIA STRUCTURE FOR VACUUM ADHESION, AND METHODS FOR USAGE AND MANUFACTURE THEREOF
Document Type and Number:
WIPO Patent Application WO/2011/065621
Kind Code:
A1
Abstract:
Disclosed are a miniature cilia structure for vacuum adhesion, having significantly improved adhesiveness and easily controlled detachability and attachability, and methods for usage and manufacture thereof. Provided for this end are a miniature cilia structure for vacuum adhesion, and methods for usage and manufacture thereof, the miniature cilia structure comprising: a substrate; miniature cilia formed on the substrate; and a vacuum adhering portion formed on the top end of each miniature cilium, and including a protrusion projecting from the miniature cilium to contact an object on which to adhere, and a recess formed in the protrusion to implement vacuum adhesion. According to the present invention, because van der Waals force, as well as capillary force or negative pressure can be used for adhesion, the adhesiveness of the miniature cilia to an object can be significantly improved. Also, detachment or adhesion can be simply controlled according to the needs of a user, without separate equipment or processes, by bending the substrate on which the miniature cilia are formed, or by controlling the angle of adhesion between the miniature cilia and the object to which they are adhered.
