Researchers have devoted a lot of efforts on pursuing light weight and high flexibility for the wearable electronics, which also requires the related energy harvesting devices to have ultrathin thickness and high stretchability. Hence, an elastic triboelectric nanogenerator (TENG) is proposed that can serve as the second skin on human body. The total thickness of this TENG is about 102 µm and the device can work durably under a strain of 100%. The carbon grease is painted on the surface of elastomer film to work as stretchable electrode and thus the fine geometry control of the electrode can be achieved. This elastic TENG can even work on the human fingers without disturbing body movement. The open‐circuit voltage and short‐circuit current from the device with a contact area of 9 cm2 can reach 115 V and 3 µA, respectively. Two kinds of self‐powered sensor systems with optimized identification strategies are also designed to demonstrate the application possibility of this elastic TENG. The superior characteristics of ultrathin thickness, high stretchability, and fine geometry control of this TENG can promote many potential applications in the field of wearable self‐powered sensory system, electronics skin, artificial muscles, and soft robotics.

具有超薄厚度和高可拉伸性的皮内摩擦电纳米发电机和自供电传感器
研究人员已经在为可穿戴电子设备追求轻量化和高柔韧性上付出了很多努力，这也要求相关的能量收集装置具有超薄的厚度和高的可拉伸性。因此，提出了一种可以用作人体第二皮肤的弹性摩擦电纳米发电机（TENG）。该TENG的总厚度约为102 µm，该器件可以在100％的应变下持久地工作。将碳脂涂在弹性体膜的表面上以用作可拉伸电极，因此可以实现电极的精细几何形状控制。这种弹性的TENG甚至可以在人的手指上起作用，而不会干扰身体的运动。接触面积为9 cm 2的设备的开路电压和短路电流分别达到115 V和3 µA。还设计了两种具有优化识别策略的自供电传感器系统，以演示该弹性TENG的应用可能性。该TENG的超薄厚度，高拉伸性和精细的几何形状控制等卓越特性可促进可穿戴式自供电传感系统，电子皮肤，人造肌肉和软机器人领域的许多潜在应用。
