In this work we show preliminary advance in the development of a low-cost wrist wearable that measures levels of oxygen saturation levels in blood (SpO 2 ) and physical activity simultaneously. For the monitoring of SpO 2 , we use pulse oximetry (a non invasive technique) by backscattering detection at the wrist. The device consists in an optoelectronics layer based on two light-emitting diodes (650nm and 960 nm) and a photodiode, a 3-axis gyroscope, a 3-axis accelerometer and a microcontroller capable of data processing and data transmission via bluetooth. In addition to, our sensor allows to save data for later analysis. |
