| Abstract |
In this paper, we propose and develop a new
real‐time human respiration process analysis method
using a high‐time‐sampling gas concentration sensor
based on ultrasound. A unique point about our proposed
gas concentration sensor is its 1 kHz gas concentration
sampling speed. This figure could not have been attained
by previously proposed gas concentration measurement
methods such as InfraRed, semiconductor gas sensors, or
GC‐MS, because the gas analysis speeds were a
maximum of a few hundred milliseconds. First, we
describe the proposed new ultrasound sound speed
measurement method and the signal processing, and
present the measurement circuit diagram. Next, we
analyse the human respiration gas variation patterns of
five healthy subjects using a newly developed gas‐masktype
respiration sensor. This reveals that the rapid gas
exchange from H2O to CO2 contains air specific to the
human being. In addition, we also measured medical
symptoms in subjects suffering from asthma,
hyperventilation and bronchial asthma. The millisecond
level high‐speed analysis of the human respiration
process will be useful for the next generation of
healthcare, rehabilitation and sports science technology. |
