The study area of our project is accurate body temperature measurement at the arm with the purpose of building an over the counter, portable device. The device is aimed towards customers who are in danger of hyperthermia or hypothermia due to their work conditions, specifically, constructions workers, hikers, and all people who are outside for long hours.
We aim for the device to be capable of monitoring temperature continuously and warning the users if their body temperature is dangerously high or low through a sound or flashing light.
NEEDS:
- Portable: without relying on a wall outlet or a laptop and remains charged, thus functional for at least 24 hours
- Frequent data acquisition: temperature data is collected often enough from the band to be effective and safe
- Affordable: pricing should be competitive with other companies with a similar purpose
- Band identification: band is identified with customer’s personalized medical history if life threatening hyperthermia/hypothermia temperatures are detected on the device
- Feedback mechanism: to alert the user if the immediate conditions are unsafe
- Waterproof: suitable for daily use, withstand sweat and splashes
- Safe to use: the material of band will be hypoallergenic and the circuitry won’t shock the user
- Durable: must withstand strong impact in high activity jobs
- Comfortable: small sized device should allow natural movement
- Wireless: able to collect temperature data independently while customer is outside without the help of a phone or wifi
- Adjustable: adequate fit for different wrist or arm sizes
- Adaptable user interface: able to change between degree Fahrenheit and Celsius readings for use in different countries
DESIGN SOLUTION:
As one of the hardware engineers on the team, I was tasked with working on the armband design using Autodesk Inventor, and creating the Printed Circuit Board using software along with soldering the circuitry to the PCB, which powered the LCD screen and feedback mechanisms.
