Standard detection methods of honey adulteration are expensive, and either have complicated operation methods or low detection accuracy. The length of the middle strip and the electric field intensity at the gaps determine the resonance frequency of the device. “When placed in the sensor, adulterated honey shifts the sensor’s resonance frequency. By measuring this shift, we can detect water adulteration in honey.”The team tested honey samples with varying water content. They found that the sensor’s resonance frequency consistently decreases with increased added water content.
