Electric current measurement using AMR sensor array
2009 International Conference on Mechatronics and Automation, 2009Anisotropic magnetoresistive sensor can be used to measure DC and AC current by sensing the field near the conductor in a contactless way. In order to improve measurement accuracy, an analysis of the influence of the displacement of the examined wire is made.

Electric current measurement using fiber-optic curvature sensor
Optics and Lasers in Engineering, 2016Abstract A novel fiber-optic curvature sensor, which can measure curvature directly, has been developed in recent years. The electric current measurements system based on fiber-optic curvature sensor and electromagnetic principle is developed. A fiber-optic curvature sensor is bonded to a thin-walled cantilever and two circular magnet targets with ...

Electrical current measurements on polystyrene films
Journal of Physics D: Applied Physics, 1974Currents decaying with time according to a 1/t law were observed in polystyrene films when a direct voltage was applied. Upon voltage removal, discharge currents were recorded, equal in magnitude to the charge currents. The currents were strongly dependent on the texture of the edges of the evaporated gold electrodes.

Direct Current Electrical Measurements
2016The physical quantities of interest in continuous current (DC) circuits are the voltage of nodes and the current flowing through branches. In addition, for the circuit analysis, the knowledge of the resistance value of its components is necessary. The instruments used to measure current intensity are the ammeters; those to measure voltage are the ...

Zeptoampere electric current measurements with molecular tagging
Chemical Physics, 2018Abstract A novel method of measuring concentrations of ionized molecules in gases that enables detection of individual ionized molecules by means of tagging them with readily detectable nano-objects has been recently discovered and developed. The femtoampere detection level of this method has been demonstrated.
