A micropump induces the flow of its surrounding fluids and is extremely promising in a variety of applications such as chemical sensing or mass transportation. However, it is still challenging to manipulate its pumping direction. In this study, we examine a binary micropump based on perovskite and poly[(2-methoxy-5-ethylhexyloxy)-1,4-phenylenevinylene] (MEHPPV). The micropump is operational under the influence of light. Light exhibits significant versatility in controlling the pumping phenomenon of the micropump. It governs the start and stop and also regulates the velocity and directions. The direction control signifies immense opportunities for the development of micropumps with unprecedented pumping behaviors and functions (such as heartbeat-like pumping, rectification, and amplification). This makes them potentially useful in various fields. Hence, it is expected that the micropump reported in the current study could act as a key step towards the further development of more sophisticated micropumps for diverse applications.

微型泵会引起其周围流体的流动，并且在诸如化学传感或大众运输等各种应用中极为有前途。然而，操纵其泵送方向仍然具有挑战性。在这项研究中，我们研究了一种基于钙钛矿和聚[（2-甲氧基-5-乙基己氧基）-1,4-亚苯基亚乙烯基]（MEHPPV）的二元微型泵。微型泵可以在光的作用下工作。光在控制微型泵的泵送现象方面显示出显着的多功能性。它控制启动和停止，还调节速度和方向。方向控制标志着具有史无前例的泵送行为和功能（例如心跳式泵送，整流和放大）的微型泵的开发机会巨大。这使得它们在各个领域都可能有用。
