This dataset contains the source data and analysis files supporting Figs. 2–5 of the associated manuscript, “A self-powered magneto-mechano-triboelectric sensor for magnetic-field anomaly detection of submarine power cables.”The dataset includes processed numerical data used to generate the figures, raw time-domain voltage records exported from NI LabVIEW, a COMSOL Multiphysics model for modal analysis, and MATLAB scripts for RMS extraction, calibration fitting, sensitivity evaluation, and signal-to-noise ratio calculation.

The files cover frequency-response measurements, structural-parameter optimisation, calibration and stability tests, and submarine-cable magnetic-field localisation experiments.Supplementary methodological files provide the theoretical model derivation, modal-simulation settings, and calibration and performance-metric definitions. All files are organised by figure number and figure panel. The top-level README.txt describes the directory structure, file formats, software requirements, and recommended procedure for accessing and processing the data.
