Folding Angle Detection
Tri-axis magnetic sensor, AK0997x is the most suitable sensor for measuring strong magnetic fields in magnets.
The magnetic sensitivity in three axis directions makes it easy to detect from which direction the magnetic field is being applied to the sensor.
Even for the complicated foldable structure using special hinges, the AK0997x can estimate a folding angle by detecting 3D magnetic variation associated with folding motion. The AK0997x is suitable for screen folding angle detection at foldable phones because it's housed in a small package and it has wide measurement range each axis.
[Note] AK09973 is recommended instead of AK09970.
