Long-term and maintenance-free operation is a critical feature for large-scale deployed battery-operated sensor nodes. Energy harvesting (EH) the most promising technology to overcome energy bottleneck of today’s sensors enable vision perpetual operation. However, relying on fluctuating environmental requires an application-specific analysis statistics combined with in-depth characterization ci...

Full optical fiber current sensor phase modulation is the use of magnetic field made the refraction different of left-handed and right-handed circularly polarized light, and the linearly polarized light can be decomposed into a left-handed and right-handed circularly polarized light. The paper proposes research and design of reflective optical fiber current sensor based on improved phase modula...
