Abstract
In accordance with disclosed embodiments, there are provided methods, systems, and apparatuses for gradient encapsulant protection of devices in stretchable electronic. For instance, in accordance with one embodiment, there is an apparatus with an electrical device on a stretchable substrate; one or more stretchable electrical interconnects coupled with the electrical device; one or more electrical components electrically coupled with the electrical device via the one or more stretchable electrical interconnects; and a gradient encapsulating material layered over and fully surrounding the electrical device and at least a portion of the one or more stretchable electrical interconnects coupled thereto, in which the gradient encapsulating material has an elastic modulus greater than the stretchable substrate and in which the elastic modulus of the gradient encapsulating material is less than the electrical device. Other related embodiments are disclosed.
