Breathefree

Stress and anxiety are among the most common challenges affecting people today and they often manifest through changes in breathing patterns. Irregular or shallow breathing can in turn lead to more serious physical and mental health issues. This project focuses on the early detection of stress and anxiety by treating breathing as a key physiological vital sign. After extensive research, we identified chest and abdominal expansion as the most accurate and non invasive method for measuring breathing rate and quality.

The developed prototype is a compact and wearable system consisting of two rectangular 3D printed enclosures fitted with force sensitive resistor sensors that measure chest and belly expansion in real time. The device operates wirelessly and transmits data to a computer via a Bluetooth dongle using serial communication. A custom Python program processes the incoming data and generates a detailed A4 sized infographic report. This report visualizes chest and abdominal breathing patterns, breathing consistency and flow, overall breathing rate, and the distribution of deep, shallow, and normal breaths, providing clear insights into an individual’s breathing behavior and potential stress levels.
