An Optical Fiber Sensor and Its Application in UAVs for Current Measurements
Sensors, 2016 In this paper, we propose and experimentally investigate an optical sensor based on a novel combination of a long-period fiber grating (LPFG) with a permanent magnet to measure electrical current in unmanned aerial vehicles (UAVs).

High Accuracy Open-Type Current Sensor with a Differential Planar Hall Resistive Sensor
Sensors, 2018 In this paper, we propose a high accuracy open-type current sensor with a differential Planar Hall Resistive (PHR) sensor. Conventional open-type current sensors with magnetic sensors are usually vulnerable to interference from an external magnetic field.

Dynamically biased current sensor for current-sensing completion detection
ISCAS 2001. The 2001 IEEE International Symposium on Circuits and Systems (Cat. No.01CH37196), 2001 This paper presents a dynamically biased current sensor for the Current-Sensing Completion Detection (CSCD) method, which cuts off the power consumption, when the logic blocks do not operate. The proposed method is an essential improvement to all completion detection methods that use static biasing in their current sensing circuits, and where the power

A High-Sensitivity Current Sensor Utilizing CrNi Wire and Microfiber Coils
Sensors, 2014 We obtain an extremely high current sensitivity by wrapping a section of microfiber on a thin-diameter chromium-nickel wire. Our detected current sensitivity is as high as 220.65 nm/A2 for a structure length of only 35 μm.
