String galvanometer
String Galvanometer
The String Galvanometer (pronounced: string gal-vuh-nom-i-ter) is a type of Galvanometer, a device used for detecting and measuring electric current. It was invented by the Dutch physician Willem Einthoven in the early 20th century and played a crucial role in the development of the Electrocardiogram (ECG).
Etymology
The term "String Galvanometer" is derived from the words "string", referring to the fine quartz filament used in the device, and "galvanometer", a term coined by the French physicist André-Marie Ampère to describe a device for measuring electric current. The term "galvanometer" itself is derived from the name of the Italian scientist Luigi Galvani, who is known for his pioneering work in bioelectricity.
Description
The String Galvanometer is a highly sensitive device that measures the minute electrical currents generated by the heart. It consists of a fine quartz filament (the "string") that is coated with silver and suspended in a strong magnetic field. When an electrical current is passed through the string, it moves in response to the magnetic field. This movement is then magnified and recorded, providing a visual representation of the heart's electrical activity.
