Abstract

A non-contact and low-cost nanomaterial based fiber-optic sensor is developed for measuring large values of electric currents. The magnetic field, generated by the electric current, changes the refractive index of a liquid in which nanomaterial particles are suspended. The change of refractive index is converted to a change in the intensity of light transmitted in an evanescent field based fiber optic sensor. The change in the intensity is proportional to the magnitude of the electric current and thus the current can be measured by measuring the resultant change in the intensity of light.
