Scientists at the University of California San Diego created a new wearable ultrasound patch that non-invasively monitors blood pressure in arteries deep beneath the skin such as the jugular vein and carotid artery. The new patch could be helpful in detecting cardiovascular problems earlier on and with greater precision. In a proof-of-concept study, the patch performed as well as some invasive means to measure central blood pressure.
The new patch uses ultrasound waves to continuously monitor central blood pressure in major arteries as deep as more than an inch below the skin, reports UC San Diego News.
If turned in a product, it may continuously monitor blood pressure changes in patients with heart or lung disease in real-time, as well as patients who are critically ill or undergoing surgeries such as cardiopulmonary procedures in which invasive methods are currently used.
“Wearable devices have so far been limited to sensing signals either on the surface of the skin or right beneath it. But this is like seeing just the tip of the iceberg,” said Sheng Xu, a professor of nanoengineering at the UC San Diego Jacobs School of Engineering and the corresponding author of the study. “By integrating ultrasound technology into wearables, we can start to capture a whole lot of other signals, biological events and activities going on way below the surface in a non-invasive manner.”
“We are adding a third dimension to the sensing range of wearable electronics,” said Xu, who is also affiliated with the Center for Wearable Sensors at UC San Diego.
