Figure 2 (IMAGE) Tohoku University Caption This study represents the stress recording (MR) function of multi-piezo mechanoluminescent material Li0.12Na0.88NbO3 through afterglow for the first time. Unlike traditional ML materials that solely enable real-time measurement of mechanical information, the novel MR capability is expected to be highly valuable for capturing the historical distribution of stress.
