Abstract:
A flexible and stretchable integrated electronic device comprising 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. A method of fabricating an integrated electronic device having a stiffness gradient comprises applying a curing agent to an uncured polymer base material.
