For a long time, people thought the Hall effect only worked when the magnetic field was applied perpendicular to the plane of the film. We've shown that that's not true: you can also get a response when the field is in-plane.

You can do multidimensional magnetic sensing with only one sensor. Before, you needed two sensors to measure the magnetic field in two directions.
