Abstract: A device includes a sensor surface and a pair of electrodes. The sensor surface includes a first conductive layer separated from a second conductive layer by an intermediary layer, a magnetization direction of the first conductive layer and a magnetization direction of the second conductive layer having a ground state orientation of approximately 0 degrees. An electrical resistance between the pair of electrodes is determined by a magnetic field proximate the sensor surface.
