A flexible and stable power supply is essential to the rapid development of wearable electronic devices. In this work, a transparent, flexible, temperature-stable and ionogel electrode-based self-healing triboelectric nanogenerator (IS-TENG) was developed. The ionogel with excellent stretchability (1,012%), high ionic conductivity (0.3 S·m⁻¹) and high-temperature stability (temperature range of −77 to 250 °C) was used as the electrode of the IS-TENG. The IS-TENG exhibited excellent transparency (92.1%) and stability. The output performance did not decrease when placed in a 60 °C oven for 48 h. In addition, the IS-TENG behaved like a stable output in the range of −20 to 60 °C. More importantly, the IS-TENG could also achieve self-healing of electrical performance at temperatures between −20 and 60 °C and its output can be restored to its original state after healing. When the single-electrode IS-TENG with an area of 3 cm × 3 cm was conducted under the working frequency of 1.5 Hz, the output values for open-circuit voltage, short-circuit current, short-circuit transferred charge, and maximum peak power density were 189 V, 6.2 µA, 57 nC, and 2.17 W·m⁻², respectively. The IS-TENG enables to harvest biomechanical energy, and drive electronic devices. Furthermore, the application of IS-TENGs as self-driven sensors for detecting human behavior was also demonstrated, showing good application prospects in the field of wearable power technology and self-driven sensing.

灵活稳定的电源对于可穿戴电子设备的快速发展至关重要。在这项工作中，开发了一种透明、灵活、温度稳定且基于离子凝胶电极的自修复摩擦纳米发电机（IS-TENG）。具有优异拉伸性 (1,012%)、高离子电导率 (0.3 S·m ^-1）和高温稳定性（-77至250°C的温度范围）被用作IS-TENG的电极。IS-TENG 表现出优异的透明度 (92.1%) 和稳定性。放入 60°C 烘箱 48 小时后，输出性能没有下降。此外，IS-TENG 在 -20 至 60 °C 的范围内表现得像一个稳定的输出。更重要的是，IS-TENG还可以在-20至60°C的温度下实现电气性能的自愈，并且在愈合后其输出可以恢复到原始状态。当面积为 3 cm × 3 cm 的单电极 IS-TENG 在 1.5 Hz 的工作频率下导通时，开路电压、短路电流、短路转移电荷和最大峰值的输出值功率密度为 189 V、6.2 µA、57 nC 和 2.17 W·m ^-2， 分别。IS-TENG 能够收集生物力学能量，并驱动电子设备。此外，还展示了IS-TENGs作为自驱动传感器用于检测人类行为的应用，在可穿戴电源技术和自驱动传感领域显示出良好的应用前景。
