Abstract
Embodiments described herein are related to contactless data communication. Related systems and methods for contactless data communication are disclosed herein. For example, a magnetic field-based contactless transmitter is disclosed that includes a substrate, a pair of dipole coils disposed on the substrate, and a drive circuit electrically coupled to the pair of dipole coils. To transmit data to a magnetic tunnel junction (MTJ) receiver disposed on a second substrate, the drive circuit is configured to drive the pair of dipole coils so as to generate a magnetic field in-plane to the MTJ receiver. Data can be transmitted from the magnetic field-based contactless transmitter to the MTJ receiver using the magnetic field.
