机器的微运动在环境、生物和医学研究中是必不可少的和有价值的。环境驱动的微动可以表现出驱动的非平衡行为。微电机在流体环境中的节能将成为分布式传感器网络的重要供电方式。在这里，我们报告了一种旋转运动的微型涡轮机作为微电机由流体动力学液体流驱动。采用飞秒激光直写技术制作了一种结构简单、可控性好的微型涡轮，该涡轮具有固定中心轴和可动叶片的结构。通过改变流速、叶片倾角、叶片长度和叶片数可以控制涡轮的转速，通过叶片的倾斜方向可以控制涡轮的旋转方向。可以设计并实现由两台微型燃气轮机组成的双联动系统。驾驭和控制运动动力的能力似乎是进一步发展流体动力流动驱动机械系统的重要要求。
The micro-motion of the machine is essential and valuable in environment, biology and medicine research. Environment-propelled micromotion can exhibit driven non-equilibrium behaviors. The energy conversation of micromotors from fluid environment would be an important power supply method for the distributed sensor network. Here, we report a kind of rotating motion of microturbines as micromotors driven by hydrodynamic liquid flow. By using femtosecond laser direct writing technology, the microturbine was fabricated, containing a simple and controllable structure of a fixed central axis and movable blades. The rotation speed could be controlled by the speed of flow, the blade tilt angle, the blade length and the blade number, and the rotation direction of microturbine could be decided by the tilt direction of blades. A dual linkage system constituted two microturbines could be designed and achieved. The ability to harness and control the power of motions appears an important requirement for further development of hydrodynamic flow-driven mechanical systems.
