[0002] With the rapid development of science and technology, the application of fluid conveying devices is becoming more and more diversified. For example, industrial applications, biomedical applications, medical care, electronic heat dissipation, etc., and even the recent popular wearable devices can be seen. It can be seen that Traditional pumps are gradually trending toward miniaturization of devices, please refer to figure 1 , figure 1 The known microelectromechanical pump module is a schematic diagram of the architecture. Although the known microelectromechanical pump module can miniaturize the volume of the microelectromechanical pump 3' to the micron level, the micron level microelectromechanical pump 3' will The amount of fluid transmission is limited, so multiple micro-electromechanical pumps 3' are required to be used together. At present, a high-end microprocessor 1' is used for individual control, but the cost of the high-end microprocessor 1' is high, and each Each microelectromechanical pump 3' must be connected by two pins, which increases the cost of the high-end microprocessor 1' and causes the cost of the microelectromechanical pump module to remain high, making it difficult to popularize. Therefore, how to reduce the cost of the microelectromechanical pump module The cost of the drive end is actually the first difficulty to overcome at present
