galvanic
意味: Relating to or producing a direct electric current from a chemical reaction, as in a galvanic cell; figuratively, causing a sudden, dramatic response or shock.
In electrochemistry, a galvanic (or voltaic) cell converts chemical energy into electrical energy through spontaneous redox reactions — every household battery is a galvanic cell. 'Galvanic corrosion' occurs when two dissimilar metals are in electrical contact in the presence of an electrolyte, causing the more reactive metal to corrode. In figurative usage, 'galvanic' describes something that jolts or energises, as if by electric shock — 'a galvanic effect on the audience.' This figurative sense derives from Luigi Galvani's famous experiments showing that electricity could make dead frogs' legs twitch.
