A new flexible, wearable medical device could provide a major boost in the fight against ラーメンベット 登録方法 disease, the leading cause of death in the United States.
A team led by researchers at The University of Texas at Austin has developed an ultrathin, lightweight electronic tattoo, or e-tattoo, that attaches to the chest for continuous, mobile ラーメンベット 登録方法 monitoring outside of a clinical setting. It includes two sensors that together provide a clear picture of ラーメンベット 登録方法 health, giving clinicians a better chance to catch red flags for ラーメンベット 登録方法 disease early.
“Most heart conditions are not very obvious. The damage is being done in the background and we don’t even know it,” said Nanshu Lu, a professor in the Department of Aerospace and ラーメンベット 登録方法 Mechanics and a lead author of the study.“If we can have continuous, mobile monitoring at home, then we can do early diagnosis and treatment, and if that can be done, 80% of ラーメンベット 登録方法 disease can be prevented.”
The study is published inAdvanced Electronic Materials.
As a continuation ofan earlier chest ラーメンベット 登録方法 project, this new version is wireless and mobile, which is enabled by a series of small active circuits and sensors carefully arranged and linked by stretchable interconnections and conforms to the chest via a medical dressing. The clear devices are far less intrusive than other monitoring systems and more comfortable for patients.
Currently, there isn’t a ready solution for long-term, comfortable monitoring outside of the clinical setting. Clinicians can run tests on patients when they visit, but they may not catch some ラーメンベット 登録方法 issues because signs of disease are not present at that moment.
The e-tattoo weighs only 2.5 grams and runs on a battery the size of a penny. The battery has a life of more than 40 hours and ラーメンベット 登録方法 easily be changed by the user.
It provides two key ラーメンベット 登録方法 measurements. The electrocardiogram, or ECG, is the electrical signal from the ラーメンベット 登録方法. And the seismocardiogram, or SCG, is the acoustic signal from the ラーメンベット 登録方法 that comes from the ラーメンベット 登録方法 valves.
ECG ラーメンベット 登録方法 be measured by mobile devices such as an Apple Watch. And the SCG ラーメンベット 登録方法 be monitored via stethoscope. But there is no mobile solution that approximates a stethoscope or takes both measurements.
“Those two measurements, electrical and mechanical, together can provide a much more comprehensive and complete picture of what’s happening with the ラーメンベット 登録方法,” Lu said. “There are many more ラーメンベット 登録方法 characteristics that could be extracted out of the two synchronously measured signals in a noninvasive manner.”
Monitoring those two factors, and synchronizing them, makes it possible to measure cardiac time intervals, which are a major indicator of ラーメンベット 登録方法 disease and other problems.
The researchers have already tested the device on five healthy patients in their day-to-day environments, with a low error rate in measurements compared with currently available ラーメンベット 登録方法 options. The next step involves further testing and validating the initial results and expanding to different types of patients.
This project rose out of a multi-university partnership of researchers who werenews ラーメンベット 出金 銀行 Archivefrom the National Science Foundation’s ASCENT program to study chest e-tattoo technology. Lu and her team have refined and adapted the e-tattoo technology to measure multiple parts ラーメンベット 登録方法 body over the years,such as the palm, and different conditions, like pneumonia.
The project team is Sarnab Bhattacharya and Philip Tan of the Chandra Department of Electrical and Computer ラーメンベット 登録方法; Alec Alden of the Department of Biomedical ラーメンベット 登録方法; Sangjun Kim of the Walker Department of Mechanical ラーメンベット 登録方法; Hirofumi Tanaka, Edward Coyle, Jieting Wang and Taha Alhalimi of the College of Education’s Department of Kinesiology and Health Education; Mohammad Nikbakht and Omer Inan of the Georgia Institute of Technology’s School of Electrical and Computer ラーメンベット 登録方法; Pulin Wang of Austin company Stretch Med Inc.; and Animesh Tandon of Cleveland Clinic Children’s Pediatric Institute.
