Flexible power supplies that can harvest power from an ambient environment are of considerable interest for future portable electronics. However, the complex structure and costly functional material of current power generators hinder their further development and practical application. Here we demonstrate flexible, all-printable graphene oxide (GO) functionalized paper as a moisture-electric power generator with an induced voltage of up to 2 V. Such high voltage is achieved by asymmetric moisturizing of GO, which enables directional ion migration across the GO. This work demonstrates a low-cost, scalable, lightweight and bendable power generator, opening up new possibilities for significantly expanding the application domain of graphene and reducing the cost of portable electronics.

氧化石墨烯的不对称加湿来发电，用于柔性，可印刷和便携式电子设备†

可以从周围环境中获取电力的柔性电源对于未来的便携式电子设备非常重要。然而，当前发电机的复杂结构和昂贵的功能材料阻碍了它们的进一步发展和实际应用。在这里，我们展示了一种柔性的，可全印刷的氧化石墨烯（GO）功能化纸，它是一种湿气发电机，感应电压高达2V。这种高电压是通过GO的不对称保湿而实现的，GO可以进行有方向的离子迁移走。这项工作展示了一种低成本，可扩展，轻便和可弯曲的发电机，为显着扩展石墨烯的应用领域并降低便携式电子产品的成本开辟了新的可能性。
