    Hi,

    I am working on some experiment to create/analyze a micro pump to deliver fluid
    I would like the fluid to deliver from a tank to the outer which is for the example, water.
    I need this pump to be in the micron size and low-power consumption
    Can you please advice for :
    a purchasing product (if there is)
    a circuit I can go over and see how to change the frequency, voltage etc...
    More than that, I would like to know which materials I need to create this circuit.

    Thanks in advance,
    Sagi

    Hello,

    What are the requirements?
    What range should the flow be?

    I think you will end up with some laboratory equipment.

    Hi,
    Thanks for the quick answer.

    What do you mean in requirement and range?

    Thanks,

    Hello,

    What kind of liquids do you want to pump?
    What amount of liquid is to be pumped?
    Is it nl/min or μl/min or ml/min or l/min.

    Greetings,
    Bertus

    Hi,

    I need to pump oxybutynin dissolved in water.
    The amount is 2mg per 24 hours in frequency of 1/min means 1.4e-3mg per minute.

    Thanks,
    Sagi

    Hello,

    You say the substance is dissolved in water.
    How many of the substance is there in a liter of water?
    How many of the liquid should be pumped?

    Hi,
    In a liter of water there is 1000mg of substrate (solubility 1mg/ml)
    The total pump should be 360ml in 6months (1 pump per minute with 1.4e-3ml per minute, 2ml a day)

    Thanks,
    Sagi

    Hi,

    Thanks for the application you propose, there is any circuit that build with the piezoelectric actuator with equation I can look at and add my variables ?

    Thanks,
    Sagi
