为保证物联网中承担着信息采集与传输等重要任务的传感器持续、稳定、免维护地工作，其中一种解决方案为收集广泛分布在环境中的振动机械能，构建自供能系统。而摩擦纳米发电机(TENG)作为机械能俘获技术之一，在收集低频无规则振动机械能方面具有更高的能量转换效率。因此，针对人行走时产生的振动机械能，设计并制作了硅胶半球支撑的接触分离式TENG。该TENG器件在1 Hz频率下的开路电压峰值为348 V，短路电流峰值为7。7 μA，外接40 MΩ电阻时瞬时功率可达265 μW，将它与树脂浇筑构建的硬质板面集成，则可实现自供能发光地板系统，能够在不同人流量的条件下正常工作。该发光地板可应用于人群密集的商场、步行街、游乐园等场所。
A Self-Powered Luminous Floor System Based on TENG
In the era of big data,a large number of sensors undertake the important task of information collection and transmission in the Internet of Things.It is an urgent problem that how to keep these sensors working steadily,consistently and maintenance-freely.Collecting vibration mechanical energy widely distributed in the environment and building a self-energy supply system,which provides a solution to the problem.As a mechanical energy capture technology,Triboelectric Nanogenerator(TENG)has a higher energy conversion efficiency in collecting low-frequency and irregularity vibrational mechanical energy.A contact-separation mode TENG supported by silicone hemispheres is designed and fabricated for vibration mechanical energy generated by walking.The open-circuit voltage peak of the TENG is 348 V and the short-circuit current peak is 7.7 μA at 1 Hz.With a 40 MΩ external resistor,the instantaneous power reaches 265 μW.When integrated with the resin pouring hard board surface,the self-powered luminous floor system can be realized,which can work normally under different human flow conditions.The luminous floor can be used in shopping malls,pedestrian streets,amusement parks and other places.
