Stretchable electronic device and method of making the same

Abstract

A method of manufacturing a stretchable electronic device includes the steps of: a) depositing a release layer on a temporary rigid substrate; b) depositing a sacrificial layer on the release layer; c) fabricating conductive traces and electrical contacts on top of the sacrificial layer; d) mounting surface mount components (SMCs) to the electrical contacts; e) depositing a first stretchable polymer layer over the conductive traces and SMCs to form a stretchable substrate; f) separating the rigid substrate and release layer from the sacrificial layer and the stretchable substrate at an interface between the release layer and the sacrificial layer; g) removing the sacrificial layer from the stretchable substrate; and h) depositing a second stretchable polymer layer on a surface of the stretchable substrate exposed by removing the sacrificial layer.
