Microwire array devices and methods for fabricating polymeric sheets containing microwires
A method for fabricating polymeric sheets containing microwires includes encapsulating at least a portion of individual lengths of a plurality of microwires in a non-conductive polymeric sheet while the microwires are attached to the substrate. The microwires are then detached from the substrate without removing the microwires from the polymeric sheet. The detaching step forms a separated polymeric sheet containing the detached microwires. Individual detached microwires of the plurality are approximately perpendicular to the separated polymeric sheet. A microwire array device includes a non-conductive polymeric sheet and a plurality of microwires. Individual microwires of the plurality have an independent length at least partially encapsulated by the polymeric sheet, are approximately perpendicular to the polymeric sheet, and contain magnetic ferrite.
METHOD FOR MANUFACTURING FILM-FORMED MOLDED PRODUCT
The present invention achieves cost reduction by simplifying the manufacturing process for a film-formed molded product provided with a metal coating film capable of transmitting electromagnetic waves therethrough. This method for manufacturing a film-formed molded product which includes a molded product and a metal coating film covering the molded product comprises: forming the molded product between a movable mold and a fixed mold; and then forming the metal coating film which covers the molded product by a film-forming part of a second mold without taking the molded product out from between the movable mold and the fixed mold.
