The island-interconnects design represents one of the categories which is widely used in stretchable electronics. Recently, Archimedean spiral interconnects are proposed as one of the best solutions for achieving a high level of stretchability. According to existing studies, their shape designs need to be investigated. Hence, this paper aims to examine the effect of the shape and the geometrical parameters of the Archimedean spiral on their stretchability. Due to the complex geometry, we use finite element method (FEM) to calculate the maximum stress and strain under axial deformation. The results conclude that with a narrow width and larger height, the Archimedean spiral shows highly stretchability more than 277% and 440% under maximum tensile strain εmax=1% and εmax=1.7%, respectively which correspond to the critical intrinsic strain of silicon. These results can be promising to fabricate high stretchable Archimedean spiral interconnects.
