Method of making arbitrarily-shaped multifunctional structure
Multifunctional structures and methods of manufacturing multifunctional structures which function as both electronic devices and load-bearing elements are disclosed. The load-bearing elements are designed to have electronic functionality using electronics designed to be load-bearing. The method of manufacturing the multifunctional structure comprises forming an electronic element directly on at least one ply of arbitrarily shaped load-bearing material using conventional lithographic techniques and/or direct write fabrication techniques, and assembling at least two plies of arbitrarily shaped load-bearing material into a multifunctional structure. The multifunctional structure may be part of an aerospace structure, part of a land vehicle, pan of a watercraft or part of a spacecraft.
1. A method of manufacturing an arbitrarily shaped multifunctional structure, the method comprising:
providing a plurality of arbitrarily-shaped load-bearing plies, wherein the plurality of arbitrarily-shaped load-bearing plies comprise at least a top ply layer and a bottom ply layer;
forming at least one electronic element directly onto a top of the bottom ply layer of at least one arbitrarily shaped load-bearing ply without employing any intervening structure using a direct-write or lithographic technique; and
coupling the top ply layer to the bottom ply layer such that the plurality of arbitrarily shaped load-bearing plies are disposed in adjacent close contact with each other to form a multifunctional structure having an exterior and an interior, wherein the multifunctional structure is an electronic device and a load-bearing element and wherein the electronic element is disposed within the interior of the multifunctional structure.
2. The method of claim 1 , wherein the multifunctional structure is conformal.
3. The method of claim 1 , wherein the multifunctional structure is flexible.
