I'm not sure this is where it should be posted, so apologies in advance, but I'm working with an Arduino and Sparkfun's heart rate monitor AD8232 (https://www.sparkfun.com/products/12650) to gather ECG data for heartrate. I want to try to collect without "official" ECG pads, and maybe without the leg option (so basically, two on the chest, opposite sides of the heart). I have been trying with tinfoil, and I get some readings with the leg lead, but it's pretty sketchy and I have to often tailor the data I gather (I am using Matlab to process the data I get, copying and pasting from the Arduino. I know I can output to a file, but, that's another story).
So I'm curious if anyone has any non-gel and non-sticky options for pad options that work?
