TL;DR: In this article, the use of prestrain in the substrate is introduced, together with interconnects in narrow, serpentine shapes, to yield significantly enhanced elastic stretchability, to more than 100%.

TL;DR: In this paper, the authors present a systematic and thorough study of buckling physics in stretchable serpentine microstructures, and a strategic design of the serpentine layout for an ultra-stretchable electrode via analytical models, finite element method (FEM) computations, and quantitative experiments.

TL;DR: This study provides theoretical guidelines for future designs of soft bio-mimetic materials with hierarchical lattice constructions by combining a finite deformation constitutive relation of the building block with the analyses of equilibrium and deformation compatibility in the periodical lattices.

TL;DR: In this article, a set of fabrication techniques and design concepts that bypass certain constraints set by the underlying physics and geometrical properties of the assembly processes associated with the original versions of these methods are introduced.

TL;DR: In this paper, the authors developed analytical models of flexibility and elastic stretchability for such structures, and established recursive formulae at different orders of self-similarity, with both demonstrating that the elastic stretch ability more than doubles when the order of the selfsimilar structure increases by one.
