Photodynamic therapy (PDT) has emerged as a promising noninvasive modality for cancer treatment.

Triboelectric nanogenerators (TENGs) have emerged as promising devices for generating self-powered therapeutic electrical stimulation over multiple aspects of wound healing. However, the challenge achieving full 100% contact in conventional TENGs presents a substantial hurdle quest higher current output, which is crucial further improving healing efficacy. Here, novel multifunctional system presented by integrating aqueous-aqueous triboelectric (A-A TENGs) with functionalized conductive hydrogel, aimed at advancing infected therapy. The A-A are founded on principle interface and efficient post-contact separation immiscible within aqueous two-phase (ATPS), enhancing charge transfer subsequently increasing performance. Leveraging this intensified demonstrates efficacies wounds both vitro vivo, including stimulating fibroblast migration proliferation, boosting angiogenesis, collagen deposition, eradicating bacteria, reducing inflammatory cells. Moreover, hydrogel ensures uniformity integrity electric field covering site, exhibits synergistic effects. With capability to realize accelerated healing, developed "A-A empowered system" presenting an excellent prospect clinical

Abstract Wave energy is a promising sustainable yet to be fully exploited due the low frequency and broad‐banded wave fields, so much that difficult capture, resulting in efficiency limited power output from current many harvesters. Here, topological defect gyro‐multigrid triboelectric nanogenerator (TD‐GM‐TENG) proposed harnesses mechanical of ocean waves generate electricity promotes accumulation charge on basis realized high rotation speed under precession gravitation acceleration effects. It benefited strategy, TD‐GM‐TENG offers transfer rate 3.1 µC s −1 when can reach nearly 1000 rpm at 1 Hz. Furthermore, density reaches 90 m − 2 cycle 0.06 s, which 1.6 times higher than same kind spherical‐TENGs field harvesting. Finally, unit outputs peak 3.7 mW simulated water environment Hz demonstrates its applicability feasibility being used as distributed emergency supply offshoring observation early warning services.

Abstract Wound healing is a complex physiological process, and if not treated in timely manner, it can lead to infections, inflammation, even risk amputation serious cases. Various methods have been developed promote wound healing. Electrical stimulation has gained significant attention for its ability cell proliferation accelerate angiogenesis. Especially, self‐powered dressings, which avoid the complexity of relying on external power sources, become one emerging approaches Materials with properties are widely used preparation dressings. This review summarizes application piezoelectric, triboelectric, thermoelectric, photoelectric, capacitive, bioelectric materials healing, focus composition, binding strategies, generation mechanisms, electrical output performance, roles tissue repair. By analyzing characteristics care applications different materials, potential advantages field elucidated, challenges facing their development discussed. provides theoretical foundation technical reference designing more efficient functionally advanced dressings future, aiming widespread clinical application.
