Bioadhesive ultrasound for long-term continuous imaging of diverse organs

Continuous imaging of internal organs over days could provide crucial information about health and diseases and enable insights into developmental biology.We report a bioadhesive ultrasound(BAUS)device that consists of a thin and rigid ultrasound probe robustly adhered to the skin via a couplant made of a soft,tough,antidehydrating,and bioadhesive hydrogel-elastomer hybrid.The BAUS device provides 48 hours of continuous imaging of diverse internal organs,including blood vessels,muscle,heart,gastrointestinal tract,diaphragm,and lung.The BAUS device could enable diagnostic and monitoring tools for various diseases.
