Abstract
Stretchable electrical devices, superior to flexible electrical devices, possess large capacity of mechanical deformability, thereby are more advantageous for biomedical and textile applications. To enhance the stretchability performance, the interconnecting wires go with serpentine geometry either in horizontal or vertical direction. The objective of the present study is to find the design rule of the stretchable electrical routing on elastomeric substrate. The simulation analysis is in agreement with the experimental studies in references, the proposed two-dimensional nonlinear model can predict the fracture occurrence of the stretched routing. The effective parameters (width W, radius R, circle angle θ and connecting length L) of routing design are discussed by simulations and experiments. The design rules of routing are presented and an optimized stretchable routing pattern is obtained.
