Antiinfective bracelet (2020)

Description

This was my final project for the course “Microcontrollers and Embedded Systems”. This project consisted of developing a solution for a specific problem presented during the COVID-19 Season, and the proposed project was about developing a special bracelet capable of detecting the tilt angle of the user's forearm and therefore knowing if the user is about to touch their face with their bare hands.

My contribution to the project was:

Developing the actual prototype This prototype was done by using an ESP32, IMU, and a mobile application, these two components were on a bracelet that the user needs to put on. The way it prevents the user to touch their face with their bare hands consists of computing the Euler angles (Pitch & Roll) from the user's forearm and then just keep constantly checking if these angles surpass the specified threshold that indicates if the user is about to touch their face if it surpasses then a buzzer make a loud sound and the mobile application sends a notification to the user's smartphone.
