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.
