- Abstract:
- The paper presents a new type of current transducer intended to measurement currents in the range of kA. Its operation principle is based on the Giant Magnetoresistance (GMR) effect occurring in multiplayer nanowires embedded in a polymer foil, providing both frequency and voltage outputs. The sensitive element works as a variable resistor mounted in a Colpitts oscillator with the oscillation frequency in the range of MHz. A negative feedback helps improving the current range and linearity
