Abstract

A method for producing a plurality of curved electronic circuits includes: producing a support including a plurality of membranes made from at least one material having a rigidity of more than around 100 MPa, each intended for being part of one of the electronic circuits and having a radius of curvature R between about 15 mm and 500 mm; applying a force to one of the main surfaces of each of the membranes, so that the membrane deforms resiliently and has a substantially planar shape when exposed to the force; rigidly connecting at least one electronic component to each of the membranes; and removing the force applied to one of the main faces of each of the membranes so that each of the membranes retrieves its original radius of curvature R and curves the electronic component according to this radius of curvature R.
