Fractal wire patterns enhance stretchability of electronic devices

(Phys.org) —Fractals—patterns defined by their scale-invariance that makes them look the same on large scales as they do on small scales—are found in nature everywhere from snowflakes to broccoli to the beating of the heart. In a new study, researchers have demonstrated that metal wires patterned in various fractal motifs, when integrated into elastic materials, enable highly stretchable electronic devices. The fractal wire patterns could lead to a variety of new devices, such as biomedical sensors that can be attached to the skin and that have unique properties such as invisibility under magnetic resonance imaging (MRI).
