Definition
Relating to the movement of a fluid (or gas) caused by the application of an electric field, often used to create propulsion without moving mechanical parts.
Etymology
The word is a compound of 'electro-' (referring to electricity), 'hydro-' (from Greek 'hudōr', meaning water or fluid), and 'dynamic' (from Greek 'dynamis', meaning power or force). It describes the physical relationship between electrical forces and the movement of fluids.
In the news
The article describes the use of electrohydrodynamic propulsion for the SPARK robots, explaining that this technology is ideal for Titan's extremely cold environment where traditional mechanical gears would likely freeze and fail.
NASA-funded flying robots could soon explore the hidden caves of Saturn's moon Titan
