Tiny ultrasound stickers continuously scan the entire body

Tiny ultrasound stickers continuously scan the entire body

According to the authors, this technology will help to create stickers and stickers that will be able to track any objects in the body through a wireless network.

The ultrasound procedures usually use thick, cold gel, which is applied to the skin before the probe is introduced. This gel is necessary for a clear transfer of ultrasonic waves from the probe to the internal organs and back.

The authors of the new work came up with a new invention, they put the hydrogel in a thin elastomer membrane, and the result is an ideal elastic material that is fixed on the skin and effectively transmits ultrasonic waves.

Elastomer prevents the dehydration of hydrogel, explains the authors.

The other part of the device contains an array of hundreds of tiny ultrasonic converters. The co-author of the study, Cheonghe Wang, said that this combination of a dense set of sensors with the elastic hybrid elastomer and hydrogel allows the device to operate in a stable manner.

Using a sticker, researchers were able to see how the stomach expands and shrinks when the volunteer drinks a glass of juice; it can also track muscles when a person lifts up gravity to inform him of a potentially traumatic exercise.

The authors want to use their Band-Aids in a mobile app and IA to automatically track and analyse the indicators.
