摘要
A three-axis magnetic sensing device included on a single chip. An example three-axis magnetic sensing device includes first and second sensing components that sense magnetic fields along two orthogonal axes planar to a surface of a substrate and a third sensing component that senses a magnetic field along an axis out of plane of the surface of the substrate. The third sensing component includes a carbon-based material. In one example, the first and second sensing components are anisotropic magnetoresistive sensors. In another example, the carbon-based material includes carbon nanotubes and the third sensing component includes a needle attached to the carbon-based material and electrodes that make contact with the carbon-based material.
