OxPal

In our Research & Development Club, my peers and I developed a device called OxPal, which measures stress levels by detecting blood volume changes using a photoplethysmography (PPG) sensor. By placing a finger into OxPal, users can measure their heart rate and heart rate variability (HRV), both indicators of stress. Additionally, we created an accompanying app that recommends personalized breathing exercises based on the measured stress levels. We showcased our work with a poster presentation at the 2024 Human-Computer Interaction Conference, and our research paper is set to be published in Springer. Furthermore, we have initiated the patent application process for OxPal.
