Inspiration

Coming from the embedded health devices section, the team was eager to find answers to the following questions:
Is it possible to build cheap devices with acual technology for medical use?
Can we build a cheap ECG (electrocardiogram) from scratch?

But how to visualize the data?
Better question:
How to perceive it?

The key is full perception through music and data curves. - But how? -> See next section

What it does

A full stack implementation of an ECG monitor, beginning by the analog signals captured from your skin ending in a remote web monitor visualizing multiple ECG devices and making them audible.
Heartbeat connects to one or more IoT devices recording an electrocardiogram to get health data from the users. The health data is visualized in a web application.

The web application also uses the heart rate to play some music - literally the sound of your heart ;)

How We built it

The Flow of our Heartbeat application roughly looks like this:

The ECG is an IoT device with soldered copper coins connected to a microcontroller.
The Microcontroller sends its data to the mBed Cloud
A Spring backend queries the data and applies filtering
The filtered data is then queried by the Angular frontend
- The frontend displays the data in a chart
- Also the data is mapped to musical notes to play some nice tune :)
