"Wearable ultrasound imaging tool would have huge potential in the future of clinical diagnosis. However, the resolution and imaging duration of existing ultrasound patches is relatively low, and they cannot image deep organs," said Chonghe Wang, an MIT graduate student,The researchers demonstrated that the sticker devices produced live, high-resolution images of major blood vessels and deeper organs such as the heart, lungs, and stomach in healthy volunteers.
"We envision a few patches adhered to different locations on the body, and the patches would communicate with your cellphone, where AI algorithms would analyze the images on demand," says the study’s senior author, The device's sticky layer is made from two thin layers of elastomer with a middle layer of solid hydrogel, a mostly water-based material that easily transmits sound waves. Unlike traditional ultrasound gels, the MIT team’s hydrogel is elastic and stretchy." The elastomer prevents dehydration of hydrogel,” says Chen, an MIT postdoc.
