William Thomson (Lord Kelvin)

Mathematical physicist & engineer

1824-1907


William Thomson, Baron Kelvin, was a Scottish engineer, mathematician, and physicist who helped to lay the foundations of modern Physics.

The magnetoresistive effect was first observed by Lord Kelvin in 1851. He discovered that the electric resistance varies upon the application of an external magnetic field. Later, in 1956 he realized that an iron plate’s electrical resistance changed depending on the direction in which the magnetisation ran. He just discovered the anisotropic magnetoresistance. Today, his findings have lead to spintronic sensing, that enables for example the measurement of the speed of a carwheel, the navigation systems or the robot control systems.

The concept anisotropic magnetoresistance is currently applied by the scientists of ByAxon in order to develop a new generation of sensors to bypass spinal cord injuries.
