Persistent mechanoluminescence (ML) with long lifetime is highly required to break the limits of the transient emitting behavior under mechanics stimuli. However, the existing materials with persistent ML are completely trap‐controlled, and a pre‐irradiation is required, which severely hinders the practical applications. In this work, a novel type of ML, self‐charging persistent ML, is created by compositing the Sr3Al2O5Cl2:Dy3+ (SAOCD) powders into flexible polydimethylsiloxane (PDMS) matrix. With no need for any pre‐irradiation, the as‐fabricated SAOCD/PDMS elastomer could exhibit intense and persistent ML under mechanics stimuli directly, which greatly facilitates its applications in mechanics lighting, displaying, imaging, and visualization. By investigating the matrix effects as well as the thermoluminescence, cathodoluminescence, and triboelectricity properties, the interfacial triboelectrification‐induced electron bombardment processes are demonstrated to be responsible for the self‐charged energy in SAOCD under mechanics stimuli. Based on the unique self‐charging processes, the SAOCD/PDMS further exhibits mechanics storage and visualized reading activities, which brings novel ideas and approaches to deal with the mechanics‐related problems in the fields of mechanical engineering, bioengineering, and artificial intelligence.

“…Previous reports have indicated the importance of X–Te and Sb–Te polyhedra similarity in doped systems, where it was appropriate to discuss bond-length similarity between Te and doped X in X–Te polyhedrons rather than lattice mismatches. 22,29,30 To clarify the correlation, the average bond length in a X–Te polyhedron was calculated, and the phase-change properties in X doped GST, including phase-change and the 10 year-lifetime temperatures, were summarized from previous reports. 31–49 Because the phase-change properties changed with doping content, the best phase-change and 10 year-lifetime temperatures were used.…”

“…V will be higher than fields. [31][32][33][34][35] According to the related research, peak voltage will increase linearly with the thickness of the PTFE film, and the thickness of the PTFE film can be adjusted by controlling the volume of the PTFE precursor and the rotation speed/time of spin coating. [12] Notably, these values are several times higher than that found in other reports, as shown in Table 1.…”

The triboelectric nanogenerator (TENG) is an emerging technology that offers excellent potential for the conversion of mechanical energy from rain into electricity for hybrid energy applications. However, a high‐performance TENG is yet to be achieved because a quantitative analysis method for the energy conversion process is still lacking. Herein, a quantitative analysis method, termed the "kinetic energy calculation and current integration" (KECCI) method, which significantly improves the understanding of the mechanical‐to‐electrical energy conversion process, is presented. Based on the KECCI method, a high‐performance TENG is developed by systematically optimizing a biomimetic surface structure and instant switch design, with 1.25 mA short‐circuit current (Isc), 150 V open‐circuit voltage (Voc), and a high energy‐conversion efficiency of 24.89%. Furthermore, a multilayered TENG device is proposed for continuously harvesting the kinetic energy of raindrops for further improvement in the energy‐conversion efficiency. Finally, the multilayered TENGs are integrated with organic photovoltaics, achieving all‐weather energy harvesting. This work presents a validated theoretical basis that will guide further development of TENGs toward higher performances, which will promote the commercialization of hybrid TENG systems for all‐weather applications.
