Abstract:
From the perspective of portable monitoring devices,we use an analog front-end AFE4490 design a module of Non-invasive blood oxygen measurement,used to colect human pulse wave signal and peak (valey) value detection and then use the principles of non-invasive oximetry calculated oxygen saturation (SPO2). This design of noninvasive oximetry module has the characteristics of smal size, low power consumption, and the results of test show that the measurement of oxygen saturation are correct.
