Design of Microwave Dual-Resonating Sensor for Chronic Wound Assessment

Abstract

Wearable microwave resonating sensors have attracted the research community in wireless communication and biomedical systems. The main objective of this paper is to assess the chronic wound such asjoint pain using such type of microwave sensor. The sensor designed to sense the abnormalities in synovial fluid, which is a main component present inside bone’s joint and avoids friction during bone’s movement and is responsible for the pain when it exhibits abnormal properties. The microwave sensor can be worn like a bandage. In this paper, FR-4 substrate is used for effective design of the resonator with high sensitivity and selectivity. For analyzing the fluid, a dual octagonal split ring resonator has been designed for the frequency of 4.611GHz. Various use cases of resonator have been simulated and the corresponding results are obtained and interpreted.
