A new graphene manufacturing process is opening up opportunities for Hall-Effect sensors says Simon Thomas, CEO of Paragraf
temperature can have on their operation. The new graphene-based Hall-Effect sensors developed by Paragraf will be able to support operational parameters that go way beyond what conventional devices can achieve. As graphene is a 2D material (with a single atom thickness) it does not have the planar Hall-Effect issues that would normally be witnessed, with only the perpendicular magnetic field being registered by the sensor element. Accuracy figures are thereby improved, with no false signals induced. Graphene-based Hall-Effect sensors therefore provide an energy-saving solution that proves far better at determining magnetic field values, while still allowing for the economies of scale that volume production enables.
