) was born in La Porcherie
and was a French physician
and inventor of the moving-coil galvanometer
and probably of the thermocouple ammeter
. D'Arsonval was an important contributor to the emerging field of electrophysiology
, the study of the effects of electricity
on biological organisms
, in the nineteenth century.
In 1881, d'Arsonval proposed tapping the thermal energy of the ocean. d'Arsonval's student, Georges Claude, built the first OTEC plant in Cuba in 1930.
d'Arsonval has a phenomenon named after him. An alternating current having a frequency of 10,000 or more per second produces no muscular contractions and does not affect the sensory nerves. It is also called the Tesla Current.
