The characterization of the POF-embedded smart textile for breath rate monitoring is achieved by performing oscillatory stretching cycles with a controlled frequency/period for 30 s. The characterization tests are performed at two different rates: six cycles and 11 cycles in 30 s. In order to obtain the respiratory rate, an FFT is applied on the signal and the peak frequency is related to the breath cycles per second. Since each gait cycle has about a 1 s duration, we limited the analysis to 12 s in order to present the cycles in detail. Previous Next Need Service Today?
