2. Prototype of a portable wireless biometric sensor Battery-powered device with fuel gauge Mounted on the wrist Monitor pulse rate, SpO 2 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. Project Abstract

3. Block Diagram

4. 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

5. 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
