In this test sample, tin-plated copper wire is embedded directly into the conductive ink regions while the ink is wet. This proved to be a more reliable electrical and mechanical bond than expected.
This is a stretchable "printed circuit board" composed of both conductive (black) and insulating (transparent) layers. The three L-shaped segments are all electrically connected to the rectangle on the bottom layer through cylindrical vias (composed of the same conductive material).
Silver (Ag) nanoflowers, 7500x magnification; these are the primary conductive material embedded within these stretchable conductors.
A completed conductive ink formulation, ready to cast.
