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.
