Nowadays, mankind faces increasingly energy crisis and electromagnetic radiation pollution. An energy harvester with function of protecting human health from electromagnetic radiation is a desirable solution to this problem. Here, a stretchable electromagnetic shielding hybrid nanogenerator (ES‐HNG) is reported which can not only scavenge thermal and mechanical energy from living environment but also protect and monitor human health. The ES‐HNG is capable of transforming mechanical and thermal energy to electricity based on triboelectric, piezoelectric, and pyroelectric effects. To be devised as a computer keyboard cover, ES‐HNG takes about 200 s to charge a capacitor to 3 V by typing. The stored energy can drive the portable devices successfully. Besides, the ES‐HNG eliminates electromagnetic radiation of computer completely due to its unique electromagnetic shielding property. A large range of electromagnetic wave (frequency is between 0 and 1.5 GHz) is shielded more than 99.9978% by the ES‐HNG. Moreover, the ES‐HNG is able to monitor human health by attaching it on human abdomen to be a self‐powered sensor. This work opens up a new prospect of harvesting energy effectively as well as protecting/monitoring human health from electromagnetic radiation surroundings.

用于健康监测和保护的电磁屏蔽混合纳米发电机

如今,人类面临着越来越多的能源危机和电磁辐射污染。具有保护人体健康免受电磁辐射影响的功能的能量收集器是解决该问题的理想解决方案。在此报道了一种可拉伸的电磁屏蔽混合纳米发电机(ES-HNG),它不仅可以从生活环境中清除热能和机械能,而且还可以保护和监测人体健康。ES-HNG能够基于摩擦电,压电和热电效应将机械能和热能转化为电能。要设计为计算机键盘盖,ES​​‐HNG需要大约200 s的时间才能通过键入将电容器充电至3V。所存储的能量可以成功地驱动便携式设备。除了,ES‐HNG具有独特的电磁屏蔽性能,可以完全消除计算机的电磁辐射。ES-HNG屏蔽了大范围的电磁波(频率在0到1.5 GHz之间)超过99.9978%。此外,ES‐HNG可以通过将其附着在人体腹部上作为自供电传感器来监控人体健康。这项工作为有效地收集能量以及保护/监测人体健康免受电磁辐射环境的影响开辟了新的前景。
