| 总结: | In this paper, a metamaterial-based resonator is proposed for the detection of dengue infection. The replaceable
top layer can measure the dielectric characteristics of blood samples to detect the dengue virus. The sensor
observed a shift in the resonant frequency towards higher frequencies with the reduction in the blood’s
permittivity. The sensor showed a 0.325 GHz shift in resonance per unit change in the dielectric permittivity. To
corroborate the sensor’s practical sensing capability, a sensor prototype was fabricated and validated with
alcohol-aqueous solutions. The sensor exhibited shifting of resonance towards lower frequencies with the
addition of water contents in methylated alcohol. With the enhanced sensitivity and repeatable measuring
capability, the results suggested that this sensor can be applied with real-time applications on the Internet of
Medical Things (IoMT) for early remote detection of the dengue outbreak.
