Health Monitor Device (EmotiBit)
Collaborators: applied Medical Device Institute (aMDI)
Oct - Dec 2022​
Abstract
This project entailed the research and development of an interface built for the EmotiBit Sensor Platform. The device developed would allow for visualization of the data being recorded by the EmotiBit, as well as customization of the data being shown to the user.
Project Requirement
-
Must gather biometric information from the wearer.
-
Must have a display.
-
Must show the data gathered in the display used.
-
Must be able to receive user input to interact with the user interface.
-
Must have customization options for the user.
-
Must be battery-operated.
-
Must be able to become attached to the user's body.
Outcomes
The EmotiBit Sensor package provides the user access to a variety of sensors. Although many are biometric data, some are not. The main feature worked on during this project was the implementation of Photoplethysmography (PPG) readings and displaying them for the user. From this PPG data some algorithms were developed to derive other useful data such as heart rate and heart rate variability. A finalized prototype was never achieved as other projects within the company took priority during my time there.
Challenges
-
Given the lack of community support for the EmotiBit sensor package, there were some challenges in getting the sensors working to begin with.
-
Additionally, finding research supporting the mathematical relationship between PPG data and heart rate variability was a challenge.
