BOTH ARM TYPE BEAM SHAPED STRUCTURE FOR DRY ADHESION AND MANUFACTURING METHOD THEREOF

摘要

A double arm shaped dry adhesion type structure and a method for manufacturing the same are provided to improve considerably its adhesion pressure corresponding to various roughness of the fine hairs and to save production cost. A double arm shaped dry adhesion type structure(100) comprises: a bottom body(110) made of flexible material able to respond to various roughness; the first post(120) established on one side of the bottom body; the second post(125) established on the other side of more than one upper board(130) separated from top side of the bottom body parallel and fixed on the post through its one side; and multiple fine hairs(140) with 50nm~5mum of diameter and 1~1000mum of length, which are formed on the upper boards.
