Professor Xuanhe Zhao at the Massachusetts Institute of Technology (MIT) and colleagues have developed a bio-adhesive ultrasonic patch (BAUS) with the ability to ultrasound a person while they are performing their daily activities. New research published in the journal Science July 28th.

BAUS is as small as a stamp, can ultrasound blood vessels, digestive system and internal organs in 48 hours, giving doctors a more detailed picture of a patient’s health than fast ultrasound images normally. In the trial, the team used the patch to monitor how the heart changed shape when the volunteers exercised, the stomach dilated and contracted when drinking, and the muscles suffered minor damage during weight training.

BAUS could “revolutionize” ultrasound because current scans are very short, sometimes only a few seconds, and often have to be done in a hospital, according to Zhao. Zhao thinks that in the future, people can buy boxes of stickers and use them with the help of smart algorithms on phones. They can monitor the heart, lungs, digestive system for early signs of illness, monitor muscles during recovery or exercise.

The patch contains a series of tiny sensors that send ultrasound waves through the skin and into the body. These waves then bounce back from blood vessels, tissues, and internal organs. Currently, the patch must be connected to an instrument that turns the echoes into images.

The team is developing a wireless version to work with the software on the phone and believe it will be successful in the next few years. Even without the wireless version, they say, BAUS makes a big difference because it allows monitoring inside the patient’s body as soon as they are in bed, like the adhesive electrodes used to monitor activity heart movement.

Ultrasound is very popular, but this technique has some limitations such as requiring highly trained medical personnel to properly place and orient the detector on the patient’s body to obtain high-quality images. . Therefore, most ultrasounds are very short and the patient is asked to lie still.

The new patches will help overcome some of these problems because they can be stuck in place and capture images for hours or even days, the team of experts say. In addition to scanning organs for early signs of disease, the patch can also monitor bladder function, tumors and fetal growth in the womb.
