Electrohydrodynamics is the science of electrically charged fluids, encompassing the study of the motion of charged particles in a variety of media. Some synonyms for electrohydrodynamics include electrophoresis, electrokinetics, and electroosmosis, which all describe the movement of particles or fluids in response to an electric field. Another synonym is electrostriction, which refers to the generation of strain in a material due to the application of an electric field, or electro-mechanical coupling. These terms are commonly used in fields such as engineering, physics, and biotechnology, where electrohydrodynamics plays an important role in the development of new technologies and scientific understanding.
