| Outline of Final Research Achievements |
The purpose of this study is to produce a precise portable sensor to monitor human respiratory rates under body motions. We carried out an impedance analysis of nanoparticle-based humidity sensors using an environmental-controlled chamber. We investigated an appropriate size of nanoparticles and coating condition. Fabricated sensors showed 2 s of response time. We fabricated a portable respiratory rate sensor using an oxygen mask. A humidity sensor chip and a data logger were attached on the mask. We showed the respiratory rate sensor could monitor respiratory rates of subjects at rest/walking/running. We also compared the sensor with a conventional instrument for respiratory monitoring and found that the monitored respiratory rates under running were valid.
