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 collect human pulse wave signal and peak (valley) 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 small size, low power consumption, and the results of test show that the measurement of oxygen saturation are correct.

The home health monitoring of the ECG signal acquisition and display terminal is designed with MSP430F6659 and ADS1298R chip of TI company. The basic principles of ECG col ection is introduced in the beginning, and then the overal scheme of the system is described by MSP430F6659 and ADS1298R chip as the core, and the modules peripheral interface, real-time display in LCD, data storage and USB are introduced. The ECG signal acquisition terminal designed in this paper has the characteristics of smal size, low power consumption and so on.
