High-tech patch warns of dangerous sodium fluctuations

A novel skin patch designed to detect critical health changes is emerging from Wiener Neustadt, Austria. Developed by material scientist Youbin Zheng and his team at the Danube Private University, the technology utilizes a micro-needle sensor to measure biomarkers in the fluid between cells.

Zheng, who leads the Laboratory for Life Sciences and Technology, aims to create tools for early diagnosis and minimally invasive health monitoring. The sensors can be adapted for various biomarkers, offering insights into the body's condition, such as sugar levels, without requiring blood draws. This innovation earned Zheng the "tecnet accent Innovation" award in April.

A key application of the patch is the continuous monitoring of sodium levels. Sodium is a vital electrolyte and a predictor of mortality in hospitalized patients, with nearly a third of intensive care patients experiencing issues with their sodium balance. Current methods rely on blood tests, which provide only snapshots in time. The patch's ability to detect critical fluctuations in real-time could be life-saving.
