"Revolutionizing Glucose Monitoring: Using a Phone's Compass for Accurate Measurements"

Researchers at NIST have developed a method to use a smartphone's compass to analyze biomarkers in body fluids, potentially allowing for the monitoring and diagnosis of diseases. In a proof-of-concept study, they successfully measured glucose and pH levels in various liquids. The technique involves a small magnet embedded in a hydrogel strip that interacts with the smartphone's magnetometer. While more testing is needed for biological fluids, this innovation could lead to affordable and portable medical sensing capabilities, with potential applications in healthcare and environmental monitoring.
