Wearable electronics suffer from severe power shortage due to limited working time of Li‐ion batteries, and there is a desperate need to build a hybrid device including energy scavenging and storing units. However, previous attempts to integrate the two units are mainly based on simple external connections and assembly, so that maintaining small volume and low manufacturing cost becomes increasingly challenging. Here a convoluted power device is presented by hybridizing internally a solid Li‐ion battery (SLB) and a triboelectric nanogenerator (TENG), so that the two units are one inseparable entity. The fabricated device acts as a TENG that can deliver a peak output power of 7.4 mW under a loading resistance of 7 MΩ, while the device also acts as an SLB to store the obtained electric energy. The device can be mounted on a human shoe to sustainably operate a green light‐emitting diode, thus demonstrating potential for self‐powered wearable electronics.

固体锂离子电池和摩擦电动纳米发电机用于自供电可穿戴电子设备的统一卷积设计

由于锂离子电池的工作时间有限，可穿戴电子设备遭受严重的电力短缺困扰，因此迫切需要构建一种包括能量清除和存储单元的混合设备。然而，先前整合这两个单元的尝试主要是基于简单的外部连接和组装，因此保持小体积和低制造成本变得越来越具有挑战性。在这里，通过将固态锂离子电池（SLB）和摩擦电纳米发电机（TENG）内部混合，提出了一种复杂的动力装置，因此这两个单元是一个不可分割的实体。制成的器件用作TENG，可在7MΩ的负载电阻下提供7.4 mW的峰值输出功率，而该器件还用作存储所获得电能的SLB。
