Abstract
A flexible and stretchable integrated electronic device includes a substrate having a stiffness gradient, wherein a rigid electronic device is embedded within the substrate. The stiffness gradient within the substrate prevents delamination at the interface between the substrate and the embedded device. The stiffness gradient is accomplished by providing at least two distinct zones in the substrate with uniform stiffness, with each zone decreasing in stiffness as in a distance from the embedded device increases, or the gradient is accomplished by having a zone with a varying stiffness.
