Abstract: A monitoring device of a sensor may obtain a first signal at a point on a first branch of a signal path of the sensor. The monitoring device may obtain a second signal at a point on a second branch of the signal path of the sensor and may monitor the first signal for first characteristics indicated by the first signal. The monitoring device may monitor the second signal for second characteristics indicated by the second signal. The monitoring device may determine whether a quantity of first characteristics indicated by the first signal without a particular quantity of second characteristics being indicated by the second signal reaches a threshold quantity of first characteristics. The monitoring device may assess functionality of the signal path based on whether the quantity of first characteristics indicated by the first signal without a particular quantity of second characteristics being indicated by the second signal reaches the threshold quantity of first characteristics.

Abstract: A device includes a magnetic layer and a guiding structure arranged over the magnetic layer and configured to sequentially transfer a skyrmion in the magnetic layer along a transfer pattern in response to a rotating magnetic field. The device further includes a plurality of magnetoresistive elements arranged along the transfer pattern and configured to detect a position of the skyrmion in the transfer pattern. The device is configured to determine a number of rotations of the rotating magnetic field based on the detected position of the skyrmion in the transfer pattern.

Abstract: The described techniques facilitate the use of a magnetic field sensor that implements the same magnetic layer stack for the detection of the x, y, and z components of an external magnetic field. The sensor advantageously is insensitive to orthogonal stray fields and operates with a reduced offset compared to conventional magnetic field sensors. The linear regime implemented by the sensor to facilitate magnetic field detection may also be adjusted per application by tuning the current strength.
