Transforming Ideas Into Reality
Project Description:
Prototype of a portable wireless health monitoring system for both hospital and residential settings.
The system focuses on monitoring patient vital parameters :
Pulse rate
SpO2 (blood oxygen saturation )
Skin temperature
Fall Detection
Features:
Automatic Alarm System
Transmit collected data via Wi-Fi
Immediate NFC access
Battery management system
Display battery longevity
Recharge the battery
Project Specific Success Criteria:
An ability to determine pulse and SpO2 readings from blood light absorption
An ability to display the users vital statistics (pulse, SpO2 , skin temperature) on the LCD screen mounted on the device which is located on the patients wrist
An ability to remotely monitor the users medical status from a web-site via secure login or authentication through an on-device NFC tag
An ability to activate an alarm both manually (through an emergency button) and automatically  in response to anomalous readings of vitals
An ability to detect if the user has suffered a fall and automatically raise an alarm
