A brand new approach to producing graphene is poised to see the wonder material gain a major commercial foothold: magnetic sensors.

Hall-Effect sensors have long been an essential component of electronic systems design, and the standard for measuring the presence of magnetic fields. They’re used for applications like steering columns or industrial motor drive systems. Hall-Effect sensors are also used in monitoring the current that flows through electrical systems like solar panels. The Hall Effect itself describes what happens when electricity flows through a material that is then exposed to a magnetic field. 

Hall effect sensors have their limitations however, mostly due to their being three-dimensional. The added depth dimension leads to false measurements and less accurate results, according to EETimes. As a 2D material, graphene is not vulnerable to the same inaccurate measuring. Hall-Effect sensors made with graphene are up to 30 times more sensitive than traditional sensors, which makes them an attractive alternative in industries from healthcare to satellite production to robotics.

Graphene-based Hall-Effect sensors not only deliver more accurate measurements, they also require less energy to function.
