The US government’s National Institute of Standards and Technology( NIST) has announced that their researchers have come up with a technique for measuring blood glucose concentration accurately through a magnetometer on a regular smartphone. Today's mobile phones are almost all equipped with a magnetometer, or built-in compass, that detects the Earth's magnetic field and provides important navigational data. These built-in magnetic compasses, when used alongside magnetic materials designed to sh
