We created a fabricatable, low-cost and accessible heart-rate monitor. This is part of our wider effort to create more accessible physiological sensors to allow for easier, wider federation of these signals into the Open Humans project.

The hardware has undergone a number of revisions since its first instanciation. You can find the versions on GitHub. The hardware is currently at most double layered to enable easy fabrication using common PCB techniques. We are currently exploring ways to fabricate these devices -along with other physiological monitors- at low cost and make them widely available as a tool for learning electronics and get more people involved in quantifying human biology.
