In this paper, we designed a device for oxygen saturation detection based on wearable technology. The wearable device is used to monitor SpO2 in real-time and temperature continuously. It consists of sensor, integrated analog front-end, mixed-signal microcontroller, solar cell, and Bluetooth module. Importantly, we adopted low-power components and optimized PCB layout design. The technology of Bluetooth Low Energy is used for data transmission from a wearable device to a smart mobile terminal (e.g., Smartphone, Pad). As for its application, the monitoring of SpO2 for outdoor activities and hypoxic diseases can be realized in this device anytime and anywhere.
