R. K. Kramer and co-authors report a direct writing method for Ga-In alloys based on an extrusion process. Liquid Ga-In exposed to ambient conditions forms a Ga-oxide skin, which governs the wetting dynamics and printability of Ga-In alloys on silicone-based substrates. The direct writing method and corresponding design algorithm developed on page 3501 lead to free-standing liquid structures, which are applied to create stretchable and conformable electronic devices.
