galvanism
- Noun:
- The therapeutic application of electricity to the body (as in the treatment of various forms of paralysis): "Galvanism" refers to the medical use of direct electric current for therapeutic purposes.
- Electricity produced by chemical action: "Galvanism" also denotes electricity generated by chemical reactions, such as in a battery.
- Noun:
- In the 19th century, galvanism was a popular treatment for nervous disorders.
- The invention of the battery demonstrated the principles of galvanism.
- "Animal galvanism": An archaic term referring to bioelectricity or the electrical phenomena observed in living tissues.
- Early experiments in animal galvanism contributed to our understanding of nerve impulses.
Galvanic (adj): Pertaining to or produced by galvanism; sudden and convulsive.
- A galvanic reaction occurred when the two metals touched the electrolyte.
- His speech had a galvanic effect on the crowd.
Galvanize (verb): To stimulate or excite as if by an electric shock; to coat iron with zinc.

- Electrotherapy: The use of electric currents for medical treatment.
- Direct current (DC): A flow of electric charge that does not change direction, as produced by galvanic cells.
Galvanic cell: An electrochemical cell that derives electrical energy from spontaneous redox reactions.
- A common battery is a type of galvanic cell.
Galvanic skin response: A change in the electrical resistance of the skin, used in lie detector tests.
- The polygraph measures the subject's galvanic skin response.
The term "galvanism" is largely historical in both its medical and scientific senses. In modern contexts: - The therapeutic sense is now covered by terms like electrotherapy or neuromuscular electrical stimulation. - The electricity-from-chemistry sense is described by electrochemistry or the operation of voltaic/galvanic cells. - The verb "galvanize" is the most common surviving form, primarily used metaphorically to mean "to shock or stimulate into action."
