Abstract
This study aimed to examine the feasibility of a portable respiratory monitoring system (PRMS) based on a micro-electro-mechanical system (MEMS). The performance of the PRMS was estimated by comparing the actual and the measured movements of the linear and the angular motions by using a one-dimensional motion phantom. The results indicated that differences between the actual and the measured movements ranged from −0.3% to −0.9% and from −7.07% to 2.93% for the periods and the amplitudes in linear motion and from −6.5% to 4.3% and from −9.5% to −5.2% for the periods and the amplitudes in angular motion. The PRMS reproduces a signal that is similar to the actual motion, and the uncertainty generated in the electronic error and the tilting movement was reduced when the velocities of movement were higher than 0.6 cm/s and 0.08 °/s. In this study, we found that the PRMS is applicable to respiratory motion training for relatively normal or fast respiratory cases and that with a more sensitive sensor, it can be the expanded to slower respiration cases.
