Compact and lightweight actuators have attracted attention for the human-machine coexistence society. However, these actuators based on conventional mechatronics mechanical elements such as motor make mechanical noise.. In this work, we propose an actuator driven by ElectroHydroDynamics(EHD). EHD is a fluidic phenomenon coupled with electrochemical reaction that can induce pressure through the application of a high-intensity electric field. The pump driven by EHD doesn’t make mechanical noise because of it doesn’t have drive part. Various EHD pumps have been developed in previous research, but all of them were not able to used any devices because of output pressure was not high. We succeeded in developing a pump driven by EHD increasing pressure by changing the electrode structure, fabricated by using a 3D printer and a cutting plotter. We obtained the pressure of 3458 Pa of EHD pump applying 8kV. EHD pump which we made was able to make approximately 9 times the output pressure campared to conventional.
