我们首先设计了一套去合金化的电化学系统来合成纳米多孔金(NPG)，并利用改进的旋转摩擦电纳米发电机(TENG)来驱动基于NPG的新型执行器。与以前报道的由于电极摩擦导致温度升高而导致输出下降的Teng相比，改进后的Teng具有稳定的输出电流和电压，分别提高了14%和20%。这种新型悬臂式混合动力驱动器具有重量轻(约3 mg)、体积小(约30 mm × 2 mm × 10 μm)的特点，由微控制器调制的Teng驱动，位移为2.2 mm，约为传统平面悬臂梁的106倍。能量转换效率定义为脱合金化和启动过程中消耗的能量与TEN输出的能量之比，分别为47%和56.7%。
We firstly designed an electrochemical system for dealloying to synthesize nanoporous gold (NPG) and also driving the novel NPG based actuator by utilizing a modified rotary triboelectric nanogenerator (TENG). Compared to the previous reported TENG whose outputs decline due to temperature rising resulting from electrodes friction, the modified TENG with a cooling system has stable output current and voltage increased by 14% and 20%, respectively. The novel cantilevered hybrid actuator characterised by light-weight (ca. 3 mg) and small volume (ca. 30 mm × 2 mm × 10 μm) is driven by a microcontroller modulated TENG with the displacement of 2.2 mm, which is about 106 times larger than that of traditional cantilever using planar surfaces. The energy conversion efficiencies defined as the energy consumed during dealloying and actuation compared with the output of TENG are 47% and 56.7%, respectively.
