| 1 | Remote Tracking Gas Molecular via the Standalone-Like Nanosensor-Based Tele-Monitoring System显示文摘Remote tracking the variation of air quality in an effective way will be highly helpful to decrease the health risk of human short-and long-term exposures to air pollution.However,high power consumption and poor sensing performance remain the concerned issues,thereby limiting the scale-up in deploying air quality tracking networks.Herein,we report a standalone-like smart device that can remotely track the variation of air pollutants in a power-saving way.Brevity,the created smart device demonstrated satisfactory selectivity(against six kinds of representative exhaust gases or air pollutants),desirable response magnitude(164–100 ppm),and acceptable response/recovery rate(52.0/50.5 s),as well as linear response relationship to NO2.After aging for 2 weeks,the created device exhibited relatively stable sensing performance more than 3 months.Moreover,a photoluminescence-enhanced light fidelity(Li-Fi)telecommunication technique is proposed and the Li-Fi communication distance is significantly extended.Conclusively,our reported standalone-like smart device would sever as a powerful sensing platform to construct high-performance and low-power consumption air quality wireless sensor networks and to prevent air pollutant-induced diseases via a more effective and low-cost approach. | Han Jin Junkan Yu Daxiang Cui Shan Gao Hao Yang Xiaowei Zhang Changzhou Hua Shengsheng Cui Cuili Xue Yuna Zhang Yuan Zhou Bin Liu Wenfeng Shen Shengwei Deng Wanlung Kam Waifung Cheung | 2021 | Nano-Micro Letters2021，13，2： | 0 |
