With the advancement of the global economy and technology, energy demand has become an urgent issue, prompting heightened attention to environmental friendliness and sustainable development. Solar energy, as a significant renewable resource, has garnered widespread attention despite facing challenges in conversion efficiency. Perovskite materials, due to their cubic crystal structure exhibiting excellent optoelectronic properties and a broad spectrum response, along with low manufacturing costs, have emerged as a recent research focus. These materials have shown remarkable potential in solar cells, light-emitting devices, and photodetectors, offering high efficiency, tunable bandgaps, and scalable fabrication processes. This study enhances the optical performance and stability of perovskite quantum dots through femtosecond pulse laser annealing technology, thereby improving their quantum yield. Advanced optical systems are employed for analysis, fully leveraging the advantages of perovskite materials in photovoltaic conversion. This research not only provides foundational solutions to pressing energy challenges but also promotes the transition of society towards cleaner and more sustainable energy technologies. Moreover, it contributes to the advancement of more efficient solar technologies, promoting innovation and development in future energy sources, and effectively reducing dependence on non-renewable energy. This is of significant importance for environmental protection, ensuring a better living environment for the future generations. © 2025 SPIE.

Highly stretchable and sensitive strain sensor based on silver nanowires/carbon nanotubes on hair band for human motion detection

引用

Progress in Natural science:Materials International 2021年第3期31卷 379-386页

作者： Yanqiang Cao Tiancheng Lai Furui Teng Chang Liu Aidong Li National Laboratory of Solid State Microstructures Materials Science and Engineering Department College of Engineering and Applied Sciences Collaborative Innovation Center of Advanced Microstructures Nanjing University Institute of Micro-nano Photonic & Beam Steering School of Science Nanjing University of Science and Technology

In this work, a highly stretchable and sensitive strain sensor using silver nanowires(Ag NWs)/multi-walled carbon nanotubes(MWCNTs) on hair band is proposed. The fabrication process of such sensors enabled scalable and facile production with low cost by dipping hair band into Ag NWs/MWCNTs composites suspension. The sensing performance of the sensors was optimized by tuning the Ag NWs/MWCNTs mass ratio. The hair band based strain sensor with Ag NWs/MWCNTs mass ratio of 30 exhibited the best performance with high sensitivity of 416.0 and good stretchability up to 70%. Moreover, great repeatability and long-term stability could be achieved over 7500 cycles of stretch-release. This Ag NWs/MWCNTs-hair band sensor can be used for monitoring human motions and swallowing action.
