Optical Fiber Magnetic Field Sensors Based on Magnetic Fluid: A Review
In this paper, the optical fiber magnetic field sensors using MF as sensing element are reviewed and the most used sensing configurations are addressed and discussed, which include optical fiber grating, interferometry, surface plasmon resonance (SPR) and other schemes involving tailored fibers.
Internal and External Temperature Monitoring of a Li-Ion Battery with Fiber Bragg Grating Sensors
This study is intended to contribute to detection of a temperature gradient in real time inside a cell, which can determine possible damage in the battery performance when it operates under normal and abnormal operating conditions, as well as to demonstrate the technical feasibility of the integration of in-operando microsensors inside Li-ion cells.
Relative humidity sensing using micro-cavities produced by the catastrophic fuse effect
Air humidity is a parameter with relevant interest to a wide variety of areas, both in industry or in domestic processes. Due to the growing demand on air humidity monitors, especially relative
