Opportunity Accurately measuring skin blood flow is essential for diagnosing and managing a wide range of medical conditions, including vascular disorders, wound healing, and peripheral circulation issues. Current measurement methods are often slow, expensive, and cumbersome, limiting their use in routine clinical care or health monitoring. Existing hardware is constrained by cost, complexity, and measurement variability. Improvements are needed to make the technology more affordable, accurate, and adaptable for real-world healthcare use. A new innovation that delivers faster, more precise, and lower-cost skin blood flow monitoring could greatly expand accessibility and improve patient outcomes across clinical and research settings.
Breakthrough in Medical Diagnostic Technology Researchers at the University of South Alabama have developed hardware improvements to a radio frequency (RF)-based apparatus for measuring skin blood flow. The new design incorporates multiple phased-array antennas for more uniform and consistent measurements. Alternative chassis designs accommodate these new configurations, ensuring both antennas and sensors remain precisely aligned with the same skin target. Importantly, the system demonstrates feasibility at lower RF frequencies which significantly reducing transmitter hardware costs compared to earlier designs. Together, these enhancements improve accuracy, reliability, and affordability, making noninvasive blood flow monitoring more practical for widespread medical use.
