Inspiration Fifa world cup coming up Smart wearables are becoming more and more prevalent Data collection becoming more valuable Reducing soccer player risk of injury What it does Uses accelerometer to measure player movement, speed, G force, and leg temperature to calibrate a measurable baseline of exertion that can be used to measure player performance and fatigue. How you built it Slimeguard is powered by 9 volt battery coupled to a voltage regulator which powers an esp32. The Esp32 collects motion data using an accelerometer and leg temperature using a thermistor in contact with the lower ankle. This data is sent to a gateway tesp32 converting wifi signals into radio waves, which is connected by usb cable to a laptop which is used to display a dashboard of the data along with a proprietary algorithm that outputs a quantified measure of a player’s performance and fatigue.
Challenges you ran into We were unfamiliar with these kinds of sensors and the corresponding firmware so the bulk of our time spent was troubleshooting and debugging. Once the sensors were able to properly function the next issue was getting the online dashboard to properly function - many hidden bugs. Accomplishments you are proud of The whole shinguard was manufactured in only a couple of hours. The product has a sleek profile, is comfortable, and is resilient to high intensity activity. Signals from the shinguard can be reliably sent over large distances
