<b>Correlating Plant Bioelectric Activity with Human Emotional States via Wearable Sensing</b>

This study demonstrates that a living plant can serve as a bio-hybrid ambient sensor for human stress states, with seven within-day correlations surviving BH FDR correction and two surviving Bonferroni correction across two independent electrode configurations. The coefficient of variation—electrode-invariant by construction—provides the most robust metric, consistently indicating that human stress suppresses the plant’s relative bioelectric variability
