Stretchable electronics is a class of electronic devices fabricated on elastomeric or flexible substrates that can sustain large tensile strain, bending, twisting, and out-of-plane deformation without loss of electrical functionality, in contrast to conventional rigid silicon-wafer electronics that fracture under even modest mechanical strain ^[1]. The devices are commonly constructed using inorganic semiconductor nanomaterials—such as silicon nanoribbons, ultrathin membranes, or wavy and serpentine interconnect structures—bonded to pre-strained elastomeric substrates so that buckling and out-of-plane wrinkling accommodate the applied strain while the active material itself remains well within its elastic deformation limit ^[2]. Alternatively, organic field-effect transistors embedded in soft elastomeric matrices and metallic nanowire networks are used to build large-area, conformable pressure and thermal sensor arrays and electronic-skin systems that can be stretched, twisted, bent, and conformally wrapped over arbitrary three-dimensional curvilinear surfaces while maintaining stable electrical conductivity and consistent electronic device performance under repeated mechanical cycling and deformation ^[3].
