in our everyday lives. Some devices already being implemented into society are biometric monitors. Such as heartrate sensors and exercise tracking devices (Fitbit‚ etc…). These can automatically connect to the internet via wireless connection (Bluetooth‚ WiFi‚ NFC) to a phone or computer and upload the data that they have been reading from your body. Such as heartrate‚ perspiration‚ distance traveled and speed‚ Calories burned‚ etc. This data can then be compared daily to see trends or can be reviewed

For commercial mobile phones with Bluetooth communication capability attached to chronic patients‚ we have developed physiological signal recognition algorithms that were implemented and built-in in the mobile phone without affecting its original communication functions. It is thus possible to integrate several front-end mobile care devices with Bluetooth communication capability to extract patients’ various physiological parameters [such as blood
