Direct-ink-writing-based 3D printing of microchannels on a 7 μm-thick elastomeric substrate was demonstrated to fabricate liquid metal microfluidic antennas with unprecedented deformability and tissue-adhesion.
Image: Development of a wirelessly powered light-emitting device based on a liquid metal microfluidic antenna. Direct ink writing (DIW) of silicone microchannels on an Ecoflex microsheet (7 μm thick) was followed by the injection of gallium-based liquid metal — Galinstan. The fabricated device showed unprecedented flexibility, stretchability, and conformal tissue adhesiveness.
Battery-free, wirelessly powered electronic devices have been developed for use in advanced medicine and healthcare. However, such electronic devices interfaced with the biological tissues are required to have an antenna for wireless communication and energy transfer.
