Multifunctional Sensitive Positive Friction Layer of TPU/MXene/STO Composited Film for Triboelectric Nanogenerator

Nano Letters, Год журнала: 2025, Номер unknown

Опубликована: Март 26, 2025

Triboelectric nanogenerators (TENGs) are ideal candidates for flexible wearable electronics due to their simple structure, high output voltage, and sensitivity. However, the of TENG still needs further improvement. This study fabricated a positive triboelectric layer with fillers improve equipped dense, irregular surface structure by using electrospinning. The effect composite filler consisting conductive MXene nanosheets ferroelectric strontium titanate nanoparticles was investigated adjusting ratio. Compared pure thermoplastic polyurethane (TPU), voltage current TMS-based (TPU/MXene/STO) increased 7 34 times. Furthermore, has been successfully applied in sensing. It can detect curvature different object grips various breathing conditions, making it promising intelligent sensing health monitoring applications. developed low-cost, high-performance, highly sensitive TENG, which shows significant potential smart devices.

Bioinspired metafilms for all-weather energy harvesting: Adaptive thermal regulation and raindrop electricity generation

Science Advances, Год журнала: 2025, Номер 11(21)

Опубликована: Май 23, 2025

Tremendous efforts have been dedicated to facilitating heat dissipation into cold universe through radiative cooling. Nevertheless, its applications remain limited by overcooling in conditions and reduced effectiveness under nonclear skies. We present a robust metafilm inspired the adaptive capabilities of horned lizards ( Phrynosoma ) overcome these challenges. This design extends energy harvesting rainy while maintaining thermal regulation on clear days. The features sandwich structure with fluorinated ethylene propylene/indium tin oxide outer layers for raindrop-induced electricity generation thermochromic core self-regulated heating It achieves an optical contrast exceeding 63% visible spectrum, enabling sub-ambient cooling hot above-ambient when cold. In addition, it demonstrates efficient droplet-induced generation, delivering high-voltage output 208 volts exceptional long-term stability. multifunctional overcomes key limitations traditional coolers, offering versatile approach all-weather harvesting.
