The rapid advancement of implantable electronics makes exploring a novel power source urgent. Self-healable triboelectric nanogenerator (SH-TENG) is an emerging and promising candidate based on the combination of triboelectric effect, electrostatic induction and self-healing action. In this work, we present a novel near-infrared (NIR) irradiation induced SH-TENG as potential implantable power source. With well-defined three-layer structure, the PDMS acts as triboelectric layer, epoxy resin-based polysulfide elastomer as healing-assisting layer, and SH/CNTs as self-healable electrostatic induction electrode layer, respectively. Due to the remotely-induced dynamic disulfide exchange reaction stimulated by NIR irradiation, the quickly generated heat can be transferred from the bottom up, leading to a zipper-like self-healing process in SH-TENG. The electrical performance, Q_sc (~16 nC), V_oc (~50 V) and I_sc (0.6 μA), respectively can be restored even after repairing for 5 times. Devices can be simply scaled up like LEGO blocks by contacting the side faces upon NIR irradiation, while scaling up the electric output performance as well. The healing process of SH-TENG has also been demonstrated through chicken skin, owing to the high penetrating ability of NIR in biological tissues which is beneficial to potential implantable electronics.

植入式电子产品的飞速发展使得探索新型电源变得迫在眉睫。自愈式摩擦电纳米发电机（SH-TENG）是基于摩擦电效应，静电感应和自愈作用的新兴且有前途的候选物。在这项工作中，我们提出了一种新型的近红外（NIR）辐射诱导的SH-TENG作为潜在的可植入电源。PDMS具有明确的三层结构，分别用作摩擦电层，环氧树脂基的聚硫化弹性体作为愈合辅助层，SH / CNTs作为可自愈的静电感应电极层。由于NIR辐射引起的远程诱导的动态二硫化物交换反应，快速产生的热量可以从下往上传递，从而导致SH-TENG中出现类似拉链的自愈过程。即使修复5次，Q _sc（〜16 nC），V _oc（_〜50 V）和I _sc（0.6μA）也可以分别恢复。通过在NIR照射下接触侧面，可以像LEGO块一样简单地按比例放大设备，同时也可以按比例提高电输出性能。SH-TENG的愈合过程也已通过鸡皮得到了证明，这是由于NIR在生物组织中具有很高的穿透能力，这对潜在的可植入电子设备是有利的。
