Figure 4

(a) Cross-sectional illustration of representative layers in a stretchable electronic system. (b) Deformations of a FS trace and distributions of maximum principal strains in the metal computed by FEA for a system consisting of electronics/UL-Sil(3.0 kPa)/fabric and electronics/PDMS (~1–2 MPa)/fabric. (c) The computed maximum principal strains in the metal as a function of the strain applied to the entire system show enhanced stretchability with the UL-Sil material compared with PDMS. (d) Scanning electron micrographs (scale bar, 200 μm) and corresponding FEA results of undeformed and uniaxially stretched (90%) configurations of a FS trace bonded to a UL-Sil/fabric substrate.
