Abstract: A sensor system includes a first metamaterial track mechanically coupled to a rotational shaft configured to rotate about a rotational axis, wherein the first metamaterial track is arranged at least partially around the rotational axis, and wherein the first metamaterial track includes a first array of elementary structures; at least one transmitter configured to transmit a first continuous wave towards the first metamaterial track, wherein the first metamaterial track is configured to convert the first continuous wave into a first receive signal based on a rotational parameter of the rotational shaft; and at least one quadrature continuous-wave receiver configured to receive the first receive signal, acquire a first measurement of a first property of the first receive signal, and determine a measurement value for the rotational parameter of the rotational shaft based on the first measurement.

Abstract: In some implementations, a sensor may determine a delay latency value associated with an amount of time from completion of a set of sensor tasks to an actual time of reception of a trigger to selectively transmit or sample sensor data. The sensor may calculate a deviation of the delay latency value from a target delay latency. The sensor may transmit a data frame including an indication associated with the deviation of the delay latency value from the target delay latency.

Abstract: A torque measurement system includes a first rotatable carrier structure and a second rotatable carrier structure mechanically coupled to a shaft; a first metamaterial track coupled to and configured to co-rotate with the first rotatable carrier structure; a second metamaterial track coupled to and configured to co-rotate with the second rotatable carrier structure; and a low-friction material arranged between the first and the second rotatable carrier structures. The first and the second metamaterial tracks are spaced apart by a predetermined distance and are mutually coupled to each other by a torque-dependent coupling. Responsive to a torque applied to the shaft, the first metamaterial track is configured to undergo a rotational shift relative to the second metamaterial track. The low-friction material provides a low-friction rotational shift between the first rotatable carrier structure and the second rotatable carrier structure such that the predetermined distance is constant during the rotational shift.
