As a part of a course I took over the summer of 2020 from John Hopkins as an exploration into Biomedical Engineering, we were tasked with creating an apparatus to measure a biomedical issue and document a procedure to solve it. 

​

Since I would spend extended periods at my desk, I created an Arduino circuit and C++ code to track my waining posture. There were two sensors, an infrared on my lower back that would find the distance between it and the chair, and an angled sensor that would be strapped to my chest to determine how much I slouched over.

​

Using this setup I took 6 different setups, kitchen chair, office chair, gaming chair, and all three with a lower back support of some kind. With the data I gathered I found that the office chair with the back support provided the least deviation from a good posture for the longest amount of time. I then collected my findings into a colorful scientific representation.
