A circular steering propulsion mechanism is proposed to explore autonomous movement of a miniature micro-vehicle with singular off-center nanoengine. The micro-vehicle comprising of gold, nickel, and platinum is invented and synthesized by layer-by-layer deposition based on the micro-electro-mechanical systems technology. The self-steering propulsion of the gold–nickel–platinum micro-vehicle is characterized in deionized water at three different hydrogen peroxide concentrations. Experimental results demonstrate that the micro-vehicle autonomously propels forward circularly in either a clockwise or a counter-clockwise direction without any external control. This research sheds light on the exploration of the self-steering propulsion achieved by the micro-vehicle with singular off-center nanoengine.

提出了一种圆形转向推进机构，以探索具有奇异偏心纳米引擎的微型微型汽车的自主运动。通过基于微机电系统技术的逐层沉积，发明并合成了由金，镍和铂组成的微车。金-镍-铂微车的自转向推进的特征在于在三种不同的过氧化氢浓度下的去离子水。实验结果表明，微型汽车在没有任何外部控制的情况下可以沿顺时针方向或逆时针方向自主地向前圆形行驶。该研究为探索具有奇异偏心纳米引擎的微车实现的自转向推进提供了参考。
