Retained and revised analysis code for boundary-dependent characterization of a fingertip-worn ERM actuator module

This code-only record provides retained custom Arduino and Python source-lineage files associated with the manuscript “Boundary-dependent command–output characterization of a fingertip-worn ERM vibrotactile actuator module with perceptual validation.” It includes retained actuator-control, psychophysical-task, MPU-measurement, and non-human physical post-processing/plotting code; data-free scripts implementing the revised physical and psychophysical analysis rules; input-schema templates; and a code-provenance document. The exact historical 21-stage acquisition snapshot was not preserved and is not represented as available. Human-subject raw data, participant-level values, demographic metadata, dates, timestamps, trial-level session files, human-data analysis inputs/outputs, and the revised Excel figure-source workbook are intentionally excluded for ethical and privacy reasons.
