The aim is to develop a high-precision sensor for monitoring low-speed motion in fitness systems.
Proposed a triboelectric rotational speed sensor (TRSS) using magnetic modulation.
Conducted performance tests to measure sensitivity and accuracy.
Validated the system through cycling experiments to assess performance over a wide speed range.
Achieved a resolution and detection accuracy of 0.21 rad s −1.
Measured sensitivity of 3.15 Hz (rad s −1) −1 with a linear correlation coefficient of 0.99892.
Observed an average error of only 1.19% in simulated tests.
