Metal-Polymer Hybrid Embroidered Microwave Multiresonator for High-Frequency Sensing: Modelling, Simulation, and Experimental Analysis

摘要

This paper presents a novel metal-polymer hybrid embroidered microwave ring multiresonator, which is implemented in a respiratory filter for high-frequency particle sensing. Metal-polymer multifilament fibres are the fundamental core for wearable technology, including bio-sensing textiles for use in healthcare and for electromagnetic shielding, which can be used in various applications. HFSS (ANSYS) was used for modelling a two-wire transmission ring multiresonator and an FEM based simulation was performed to analyze different coupling methods. Following this, the design and manufacture of the embroidered sensor is described. After that, a scatter analysis was made of the measured parameters from 2-8 GHz and the quality factors. In a case study, beech dust particles were used to load the respiratory filter to characterize the performance of the implemented ring multiresonator.
