Method for accurate and low-consumption mems micropump actuation and device for carrying out said method

A method for actuating a pumping system to improve fluid delivery accuracy, the pumping system including,

• a pumping chamber having an inlet channel and an outlet channel, a pumping membrane in operative connection with the pumping chamber, an actuator operatively coupled to the pumping membrane configured to be pushed by the actuator to generate a positive pressure of a fluid in the pumping chamber and configured to be pulled by the actuator to generate a negative pressure of the fluid in the pumping chamber, and a pump controller configured to control the actuator according to a pumping pattern including a first pumping cycle and a second pumping cycle,
• the first pumping cycle beginning by a partial push and ending by a partial push of the membrane by the actuator, and
• the second pumping cycle beginning by a partial pull and ending by a partial pull of the membrane by the actuator,
• wherein the method includes the steps of:
• performing a first determined number of the first pumping cycle followed by a second determined number of the second pumping cycle or vice versa.
