Design Principles

"Material and structural design of conductive elements must account for operational mechanical stresses to ensure functional integrity."

Stretchable circuits are critical for the development of advanced wearable electronics and human-computer interfaces. Ensuring their reliable performance under dynamic conditions requires careful consideration of how the conductive elements, particularly electrodes, behave when stretched, bent, or twisted.

What This Means for Your Design

To make electronic circuits that can stretch without breaking or losing power, you need to use special stretchy materials and arrange them in clever ways, like making them wavy, so they don't snap when pulled.
