Galvanometer mechanisms are currently used to position the pens of analog chart recorders such as used for making an electrocardiogram.

An electrocardiogram (ECG) is a graphic produced by an electrocardiograph, which records the electrical voltage in the heart in the form of a continuous strip graph. It is the prime tool in cardiac electrophysiology, and has a prime function in screening and diagnosis of cardiovascular diseases.

Also, if required:

An ECG is constructed by measuring electrical potential between various points of the body using a galvanometer. Leads I, II and III are measured over the limbs: I is from the right to the left arm, II is from the right arm to the left leg and III is from the left arm to the left leg.


ECGs are those beeping machines you see in movies and TV, it measures the person's heart beats (duh) and so you can imagine what impacts galvanometers have on society, ;)
