WebThe design of the micropump was mainly divided into two major components, which were the actuation mechanism and the fluidic network. The proposed design of the micropump system consisted of two identical 35 mm diameter with 0.3 mm thick circular PZT actuated metal diaphragms as actuators. The thickness of the PZT disk was 0.22 mm. WebJul 27, 2016 · The highest no-load velocity is also exhibited by the PMN-based actuator (270 mm/s). The maximum output power obtained is 2.5 W for both PMN and Terfenol-D-based actuators while the highest electromechanical efficiency obtained is 7% for the PMN-based actuator.
