Abstract

This paper proposed a wearable throat vibration system using a microwave sensor. Compared with millimeterwave measurement systems, a simple split-ring resonator can clearly detect and evaluate vocal fold vibration in the industrial, scientific and medical band. Higher harmonics can still be identified and quantified. A high-sensitivity microwave split-ring resonator has a sharp resonance response corresponding to the variation of the electrical fields timely in the near field to detect throat vibration. The use of amplitude modulation can be detected using an envelope detector at low cost and sensitively senses details of the vibration from vocal fold. Finally, the actual measurement results prove that the microwave sensor can measure approximately eleventh harmonics.
