Human machine interface (HMI) devices, which can convert human motions to electrical signals to control/charge electronic devices, have attracted tremendous attention from the engineering and science fields. Herein, the high output voltage from a nonpiezoelectric meso‐poly(lactic acid) (meso‐PLA) electret‐based triboelectric nanogenerator (NG) is combined with the relatively high current from a double‐layered poly(l‐lactic acid) (PLLA)‐based piezoelectric nanogenerator (PENG) for an E‐skin (electronic skin) (HMI) device application. The hybrid NG with a cantilever structure can generate an output voltage of 70 V and a current of 25 µA at the resonance frequency of 19.7 Hz and a tip load of 4.71 g. Moreover, the output power of the hybrid NG reaches 0.31 mW, which is 11% higher than that from the PLLA‐based PENG. Furthermore, it is demonstrated that the PLA‐based hybrid NG can be used to turn a light‐emitting diode light on and off through an energy management circuit during a bending test. Finally, it is demonstrated that the PLA‐based woven E‐skin device can generate the output signals of 35 V (V_oc) and 1 µA (I_sc) during an elbow bending test. The advantages of biocompatible, ease of fabrication, and relatively high output power in the hybrid NG device show great promise for future E‐skin applications.

生物相容性基于聚乳酸的压电和驻极体混合纳米发电机，用于电子皮肤应用

可以将人类运动转换为电信号以控制/给电子设备充电的人机界面（HMI）设备已经引起了工程和科学领域的极大关注。本文中，非压电介孔聚乳酸（meso -PLA）驻极体摩擦纳米发电机（NG）的高输出电压与双层聚（l基于乳酸（PLLA）的压电纳米发电机（PENG），用于电子皮肤（电子皮肤）（HMI）设备应用。具有悬臂结构的混合NG可以在19.7 Hz的共振频率和4.71 g的尖端负载下产生70 V的输出电压和25 µA的电流。此外，混合天然气的输出功率达到0.31 mW，比基于PLLA的PENG的输出功率高11％。此外，已证明基于PLA的混合气体NG可在弯曲测试过程中通过能量管理电路打开和关闭发光二极管的光。最后，证明基于PLA的编织E皮肤设备可以生成35 V（V _oc）和1 µA（I _sc）在肘部弯曲测试中。混合NG设备具有生物相容性，易于制造以及相对较高的输出功率的优势，为未来的电子皮肤应用展示了广阔的前景。
