Claim of US Patent No. 10,462,897

1. A method of making an integrated electronic device having a stiffness gradient, the method comprising:embedding a rigid electronic device in a substrate comprising an uncured polymer base, and
applying a curing agent to the substrate in a pattern,
wherein applying the curing agent in the pattern creates a portion of the substrate adjacent the embedded electronic device with a modulus in between a modulus of a portion of the substrate not adjacent to the embedded electronic device and the modulus of the rigid electronic device.
