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
