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.
Claims7
An integrated electronic device comprising:
- a substrate comprising a first section and a second section,
- a rigid electronic device is embedded in the substrate,
- wherein the first section of the substrate is adjacent to the rigid electronic device and has a uniform stiffness,
- wherein the second section of the substrate is peripheral to the first section and a has a stiffness gradient with a maximum stiffness at an interface with the first section.
