New technology could better monitor blood pressure
CINCINNATI (WKRC) - New technology that could help better monitor blood pressure is in the works.
The National Institutes of Health has just released a photo of a wearable device that might soon help detect the pressure of blood flowing through your arteries.
A blood pressure cuff is traditionally placed around the arm to measure your blood pressure at the doctor's office, or you may even have a finger checker at home, but this new patch is different.
It was developed by a team at the University of California, San Diego. The lead researchers Dr. Sheng Xu and his team shared a photo of the patch so to speak, which can be worn a couple of different ways.
It is a thin, wearable blood pressure sensor that uses ultrasound transducers, according to the NIH. A transducer makes high-frequency sound waves. These bounce off the blood vessel. The transducer then receives echo patterns and sends them to a computer. The computer then converts it into a waveform. If the waveform is calibrated to a patient's blood pressure, changes would then show up.
The team engineered this stretchy, flexible device to do all this. It can be worn as a skin patch. An array of ultrasound transducers selects an artery from the best position. They also have a layer of silicone beneath the patch so you don't have to use a gel as you usually do with conventional ultrasound wands.
Most of these wearable devices have barely gone beneath the skin. This one, however, can monitor below it. Researchers are hoping to make it wireless to share data.
