英文摘要	With the rapidly increasing health and environmental awareness, demands for wearable electronics are no longer limited to performance and design, but also safety, health and environment protection. Herein, a sustainable and shape-adaptable skin-like liquid single-electrode TENG (LS-TENG) is developed using aloe vera gel (AVG)@NaCl as the liquid electrode. As an effective network channel for charge transfer, the liquid electrode shows high conductivity and mobility, leading to a high current density that is 2.1-23 folds of reported LS-TENGs. Besides, the size effect of liquid electrode in LS-TENG is firstly investigated, upon which the output parameters are optimized. Consequently, AVG@lwt%NaCl-based LS-TENG shows the highest output reported for LS-TENG with V-OC of 157.8 V, J(SC) of 44.2 mA/m(2) and power density of 4.61 W/m(2). Moreover, the device shows a high sensitivity to minute face expressions and is suitable for 2D or 3D-shape fabrication, indicating a great potential for use in wearable electronics, such as e-skin and health monitoring.
