delivery and flow of gases. Since the compressibility of the gases is challenging, the micropump must possess high compression ratio. Among other applications, the following fields can be named: dosage systems for small quantity of lubricants, fuel dosing systems, micro pneumatics, micro hydraulic systems and dosage systems in production processes, liquid handling (cushion pipettes, microliter plates).
