Self-restoring, waterproof, tunable microstructural shape memory triboelectric nanogenerator for self-powered water temperature sensor

The thermal induced temporal changes of microstructured shape memory polymer for self-recovery triboelectric nanogenerator can be indigenously harnessed for water energy harvesting and water temperature sensing, simultaneously. Here, tunable microarchitectures of a thermally triggered shape memory polymer are realized by electrospinning, namely mats of microfibers (MFs), microspheres (MSs), and microspheres-nanofibers (MSNFs). The tunable...
