Electrorheology refers to the study of the fluids' flow and mechanical behavior under an applied electric field. Some synonyms to the term electrorheology include electro-fluid-dynamics, electroviscous mechanics, electrokinetic rheology, and electrophysicology. Electro-fluid dynamics examine the fluid's behavior in the presence of electric fields, whereas electrokinetic rheology studies their mechanical properties. Electrophysicology deals with the fluid's electrical and physical properties and the interaction of electric fields with the fluid's motion. These terms are often used interchangeably but refer to distinct aspects of fluid dynamics under electric fields. The study of electrorheology has several applications, including fluid control systems, medical devices, and material processing.
