Fractal-Inspired Design on Substrate for Stretchable Electronics

In Chap. 5, the bonding configuration of self-similar serpentine interconnects on the elastomer substrate is considered. The stretchability of the order-2 self-similar interconnects bonded onto the PDMS substrate is studied through analytical modeling, finite element simulations, and experiments. The scaling law is built to predict the stretchability of the structure. Then, the application of self-similar interconnects in surface electrodes is introduced to design surface electrodes with high mechanical adaptability (stretchability and conformability with skin) and high electrical sensitivity/stability which are usually a pair of paradoxes.
