Split Ring Resonator Sensor Design for Real-Time Breathing Monitoring

Abstract

In this paper, we present a Split ring resonator-based sensor for real-time breathing monitoring application. The design aims at detecting various serous health conditions like sleep apnea, sudden infant death syndrome, cardiac arrest and so forth. The design is based on a microstrip technology along with the split ring resonator and coupling line techniques. The sensor was designed to operate at 0.8 GHz and 1.4 GHz. The substrate utilized in the design is Rogers RO3010, which has dielectric constant of 10.2 and a thickness of 1.27 mm. Simulation findings show that the sensor performs as expected and demonstrate its functioning at the desired design frequencies.
