Facile Preparation of High-Performance Elastically Stretchable Interconnects

Sites on poly(dimethylsiloxane) are selected by ultraviolet exposure. In a subsequent electroless deposition, solid silver films are created on the selected sites only. In this way, facile vacuum-free deposition of electrodes from the liquid phase and their photoresist-and solvent-free patterning are realized. The technique enables reliable rigid-to-soft interconnects that are reversibly stretchable under arbitrary and changing stretching directions.
