In response to the energy crisis, it is of great significance to develop spontaneous electric generation devices and apply them in the field of wearable and self-powered devices. Due to their advantages of being non-polluting, with simple structure and wide application conditions, moist-electric generators (MEGs) have received widespread attention. However, MEGs have been inevitably faced with the drawbacks of low content of active groups, short lifetime, and poor flexibility after assembly into devices, which limit their development into broader applications. In this work, sucrose-sulfonated carbon (SC) containing numerous strong Brønsted acid sites (–SO₃H) was used to prepare ME membranes (PSM) and develop rigid and flexible membrane-type moist-electric generators (SC-MEG). The SC-MEGs can provide a high voltage of 0.62 V and a current of 2.5 μA cm⁻² at 70% relative humidity change (ΔRH). In addition, SC-MEGs can be made into larger chain integrated power supplies (CIPS). A CIPS containing 10 SC-MEGs can provide an outstanding 6 V output voltage and can be tailored to the desired voltage output. These characteristics allow SC-MEG to be used in a wide range of portable wearable electronics. Our design provides a novel idea for the design of self-powered electronic devices.

来自含有强布朗斯台德酸位点的磺化碳固体酸的高性能灵活和可集成的 MEG 设备

应对能源危机，开发自发电装置并将其应用于可穿戴和自供电设备领域具有重要意义。湿式发电机（MEGs）因其无污染、结构简单、应用范围广等优点而受到广泛关注。然而，MEGs不可避免地面临着活性基团含量低、寿命短、组装成器件后柔韧性差等缺点，限制了其向更广泛应用的发展。在这项工作中，蔗糖磺化碳 (SC) 含有许多强布朗斯台德酸位点 (–SO ₃H) 用于制备 ME 膜 (PSM) 并开发刚性和柔性膜式湿电发电机 (SC-MEG)。SC-MEG 可以在 70% 的相对湿度变化 (ΔRH) 下提供 0.62 V 的高电压和 2.5 μA cm ^-2的电流。此外，SC-MEG 可以制成更大的链式集成电源 (CIPS)。包含 10 个 SC-MEG 的 CIPS 可以提供出色的 6 V 输出电压，并且可以根据所需的电压输出进行定制。这些特性使 SC-MEG 可用于各种便携式可穿戴电子产品。我们的设计为自供电电子设备的设计提供了一种新颖的想法。
