Monitoring Brain Blood Flow with a Wearable Ultrasound Patch
University of California San Diego engineers have developed a wearable ultrasound patch that can offer continuous, non-invasive monitoring of blood flow in the brain. Watch this video to learn more about this soft and stretchy patch that can be comfortably worn on the temple.
“The continuous monitoring capability of the patch addresses a critical gap in current clinical practices,” said study co-first author Sai Zhou, a materials science and engineering Ph.D. candidate in Xu’s lab. “Typically, cerebral blood flow is monitored at specific times each day, and those measurements do not necessarily reflect what may happen during the rest of the day. There can be undetected fluctuations between measurements. If a patient is about to experience an onset of stroke in the middle of the night, this device could offer information that is crucial for timely intervention.”
