Abstract
A method and a sensor for detecting or measuring at least one specific component among a plurality of components present in a gaseous or liquid mixture by a sensor having at least one capturing cell with a high-electron mobility transistor including a source and a drain with a grid inserted between the source and the drain, a voltage being applied between the source and the drain, and a current intensity in the capturing cell being recorded. The voltage between the source and the drain is controlled, which varies the intensity of the current, the voltage being controlled according to a voltage model predetermined by experience in order to provide a profile with an intensity which is characteristic of said at least one specific component.
