Mechanical and electrical responses of noncoplanar stretchable electronics to twisting deformations. (A) Optical images of an array of stretchable CMOS inverters in a twisted configuration (Left) and magnified view of a single inverter, illustrating the nature of the deformation (Right). (B) FEM simulation of the mechanics of twisting on the bridge structures. (C) SEM image of an array of stretchable, 3-stage CMOS ring oscillators in a twisted configuration. (D) Electrical characteristics of the inverters (Upper; gain and output voltage, Vout, as a function of input voltage, Vin) and oscillators (Lower; output voltage, Vout, as a function of time) in planar and twisted states.
