The main purpose of this study is to develop a lightweight and compact fluid actuator which makes use of such properties of EHD fluid. We think that it is useful to apply EHD actuators to a micro actuating system as a lightweight actuator. In order to develop such an actuator, we first...
A Compact Electrohydrodynamic Pump Using Copper And TPU June 9, 2024byMaya Posch21 Comments Electrohydrodynamics (EHD) involves the dynamics of electrically charged fluids, which effectively means making fluids move using nothing but electric fields, making it an attractive idea for creating a pump ou...

The positions of our EHD pump and EHD fluid level in the reservoir were set to the same height. After applying DC voltage (Matsusada Precision Inc.), we measured the height difference (h) and calculated the output pressure (P) by the equation: P=ρgh, where ρ and g are the density ...
For computational fluid dynamics (CFD) numerical simulation, a complex control equation system is necessary for restoring the flow field in the centrifugal pump under real working conditions, and the high computational cost and difficulty converging of technologies such as fluid–structure interaction ...
Pumping of solutions was accomplished using a set of multi-channel peristaltic pumps and a two-channel syringe pump. For demonstrations requiring a shorter run-time, the higher-accuracy Harvard Apparatus Elite 11 syringe pump was preferred for the feed solution while the peristaltic pumps were ideal...
Fluid Model [1, 2] EHD and EMHD Transport Processes in a Neutral or Charged One-Component Fluid: Single Fluid Model [1, 2]EHD and EMHD Transport Processes in a Neutral or Charged One-Component Fluid: Single Fluid Model [1, 2]One-component fluid is a continuum consisting of a single ...
Electrospinning, also known as electrostatic spinning, is a powerful, rather simple and highly versatile technique which allows fabricating micro- and nanoscale fibers from process solutions or melts using an electrically forced fluid jet (Fig. 1) [37], [38], [39], [40]. The diverse properties...
As a result of the increased osmotic pressure, fluid flows toward the membrane from the sides and up at the center of the film, with the film effectively operating as a fluid pump. The scheme is shown in Fig. 3a. The release of chemical signals can be made autocatalytic, as shown by ...
Usually, EHD printing consists of a high-voltage power supply, a high-speed camera, and an air pump connected to a printing table. During EHD printing process, high voltage is applied between the nozzle and substrate, while the nozzle is connected with the positive pole of the high voltage ...
