Researchers have created a flexible, wearable ultrasound patch that can measure the blood pressure deep within the body.
Although central blood pressure is more accurate than peripheral (which is read by an arm cuff), measuring central blood pressure requires invasive or questionably-accurate measures.
As an alternative, a team from the University of California developed a flexible ultrasound patch made up of an elastomer sheet embedded with electrodes linked by springy bridges of copper wire. Once applied to the patient’s skin, the patch will continuously monitor the pulsing of major arteries as deep as more than an inch beneath the skin. That data is then processed in real time by a hardwired processing unit that translates the information into a central blood pressure reading.
