Abstract
Improved stretchable printed circuit boards, and fabrication methods thereof, are described. The improved stretchable printed circuit boards include a serpentine conductive trace enclosed by stretchable dielectric material. The stretchable dielectric material has a serpentine shape itself, realized by crenulated edges. The crenulated edges reduce torsional strain on the conductive trace and are formed, for example, by cutting away sections of the stretchable dielectric material proximate segments of the serpentine conductive trace where the serpentine conductive trace changes direction.
