KeepSafe - Wristband Device for Heart-rate Monitoring

The goal of this project is to meet efficient and technological management solutions that allow to increase life quality of elderly people and at same time reduce costs in the health sector. The KeepSafe® wristband device will increase the safety of users since it will be able to continuously monitor vital signs and it will generate dynamic alerts based on thresholds or manual alerts by pressing a SOS button. The device uses a reflective PPG (Photoplethysmogram) technique using two green LEDs and a photodiode sensor on the wrist to continuously estimate heart rate. Then this data is correlated with the activity data estimated by an accelerometer and gyroscope. All data is sent to a smartphone via Bluetooth® Smart. The future goal is to make the device autonomous by adding GSM communication capabilities.
