    Self-powered sensing related to triboelectric nanogenerator (TENG) as a sustainable self-sufficient power source for environmental monitoring by harvesting energy from a living environment is critical in the field of energy and environmental science. However, features of small energy-density and irregularity of environmental energy make it difficult to use directly for real-time environmental monitoring. Here, we report a self-powered and self-calibrated e... ...点击完成人机验证后继续浏览

    自供电传感技术与摩擦纳米发电机(TENG)作为可持续的自给电源,通过从生活环境中获取能量来进行环境监测,在能源和环境科学领域至关重要。然而,由于小能量密度和环境能量的不规则性,直接用于实时环境监测存在困难。在这里,我们报道了一种由TENG、校准电阻和并联传感器网络组成的自供电和自校准环境监测系统(SSEMS),用于实时温度和湿度监测。校准电阻可以实时监控由于降雨不规则性导致的TENG输出波动。SSEMS利用这一校准信号来实时校准传感信号,实现误差小于5.0%的准确感应。我们在瀑布和雨中应用了SSEMS,以实时监测环境温度和相对湿度,并将感知误差降低至1.0%。这项工作推动了自供电技术向实际应用迈出了一步。
