Historically, ultrasounds have been done by using “wands and probes to direct sound waves into the body” which gives clinicians a look into their patient’s internal organs. A new design out of MIT could change this technology. MIT engineers presented Science with their design of an “ultrasound sticker – a stamp-sized device that sticks to skin and can provide continuous ultrasound imaging of internal organs for 48 hours.” When applied to the skin, the ultrasound stickers “showed the devices produced live, high-resolution images of major blood vessels and deeper organs such as the heart, lungs, and stomach. The stickers maintained a strong adhesion and captured changes in underlying organs as volunteers performed various activities, including sitting, standing, jogging, and biking.” This invention could make ultrasounds much more accessible, convenient, and affordable.
