No methods describing the variation of the electrical properties of stretchable interconnects depending on their extension are available for use in the design and technology transfer process of flexible electronic systems. A calculation method to extract the parasitic parameters of a wire is proposed herein based on the skin-depth effect and the deformation of the wire, and a one-\(\uppi \) equivalent circuit model obtained, establishing a new analytical model for stretchable interconnects. Moreover, a flexible electronic design platform is also presented. The numerical model was used to analyze the variation trends of electrical properties of a stretchable interconnect using the proposed flexible electronic design platform. Finally, the validity of the proposed model within a tolerance of 3% was proved by comparing the simulation results with measurements, demonstrating that the proposed model and extracted parameters accurately characterize such flexible interconnects over a wide frequency range up to 10 GHz. Thus, the proposed model can be easily applied to design flexible electronic systems.
