A micropump is a tiny machine that helps to move fluids from one place to another. It is like a little robot that works hard to push liquids around. Imagine your bathtub drain opening and the water rushing out. A micropump does the opposite by pushing water (or any other liquid) in a particular direction. It can be used for many different things, like in medical devices to deliver the right amount of medicine or in laboratory tests to move fluids in a precise manner. So, it's like a small helper that works quietly and tirelessly to move liquids where they need to go.
