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, which consists of a thin and rigid ultrasound probe robustly adhered on the skin via a couplant of a soft, tough, anti-dehydrating and bioadhesive hydrogel-elastomer hybrid. The BAUS device provides 48-hour 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.
