Monitoring System for Causative Substance of Underarm Odor Using a Multimodal Sensor

Abstract

This paper proposes a novel monitoring sensor for the pH characteristics of the substance that causes underarm odor. The multimodal sensor, which can measure electrical impedance, temperature, and pH, and the AgCl reference electrode were adopted in the system to measure the substance’s pH on the skin. The experimental results showed that the proposed system may be able to accurately measure the pH value.
