摘　　要：Stretchable electronics are of huge interest as they can be useful in various irregular non-planar or deformable surfaces including human bodies.High density multi-functional stretchable electronics are beneficial as they can be reliably used in more compact regions.However,simply stacking multiple layers may increase induced strain,reducing degree of stretchability.Here,we present the design approach for the stretchable multilayer electronics that provide a similar degree of stretchability compare to a single layer electronics although the multilayer electronics are in much more compact form.We provide experimental and computational analyses for the benefits of the approach along with demonstrations with compact form of the multi-functional stretchable implantable bio-electronics and of the stretchable multilayer passive matrix LEDs array.The results presented here should be useful for a wide range of applications that require stretchable high-density electronics.
