The idea isn't new, but the size and scope of it is. Ultrasounds can heat up molecules in skin tissue, creating a more permeable space for drugs to pass through. The staff at biomedical engineering company Zetroz have taken that and created the uPill, an ultrasound-powered pill that can speed up the drug absorption process. A person would swallow the pill, coated in the necessary drug, and ultrasound waves would prime the stomach for absorption. After that, the pill would pass through the digestive system.
