Project Abstract
• Prototype of a portable wireless biometric sensor
• Battery-powered device with fuel gauge
• Mounted on the wrist
• Monitor pulse rate, SpO2 and skin temperature
• Transmit the information via Wi-Fi for remote web access
• NFC chip allows immediate access
• Accelerometer on the shoulder for fall detection
• Manual and automatic alarm system.

Environmental Impact
• PCB Fabrication
– Exposure to hazardous chemicals during manufacture
– Small PCB minimizes impact
– EU addressing the situation through RoHS and WEEE
• LiPo
– More durable than Ni-Cd batteries but can still explode when
overcharged
– Difficult to recycle
• Power Consumption
– Very low powered device
– Limit the use of Wi-Fi
– Use of servers for web hosting
Ethical Issues
• Calibration
– Ensure sensors report correct readings and conform to all existing
standards
– Extensive testing phase
• Safety
– Built in system redundancies to mitigate the failure of high risk
components
– Ensure that our device does not affect patients with medical devices like
a pacemaker.
• Privacy
– Handle sensitive medical data
– Provide proper safeguards to prevent misuse
