@victus I haven't seen anyone using CC2561 - almost everyone is using AtMega328 or ESP8266. MySensors does not utilize ble. Therefore this might not be the best forum to ask for advice, unfortunately. But there are a lot of hardware nerds around so you might get lucky.

@victus I'd suggest you start with their patented technology. I couldn't find it, but I found similar applications like http://www.google.com/patents/US20130109931 Apparently bending of the fiber attenuates a ray of light going through it. A photo sensor measures the attenuation and some microcontroller draws the conclusions. Not very hard to do, I think.

@victus Im not familiar with this components you mention, you need to test yourself, cant help you with the technical stuff. It does not seem to be a fully functional ECG but a heart rate monitor. As epierre said above, you need to define if you want to monitor or have a fully functional ECG, its a big difference. With a monitor all you get is pretty much your heartrate and you can detect arytmias. A fully working ECG is normally made with 12 leads and is used to in detail know how the electrical depolarisation from different time and direction/place within the heart muscle works. Holter is a example of a heart rate monitor over time.
