【 摘 要 】
A novel microwave sensor for real-time analyte composition analysis is reported. The sensing element in a form of silver pattern was printed on polyimide flexible laminate substrate to suit a broad range of applications where a sensor could be placed in water reservoirs or fluid-carrying pipes for continuous analysis. The developed system confirmed the viability of using microwaves for real-time NaCl monitoring as the reflected signals represented by S11parameters corresponding to deionised water and 0.1M and 0.01M of NaCl were unique with clearly observed shifts in the resonant frequencies when placed in direct contact with 20 μl of each solution.
