Problem The AD8232-based EKG breakout board is a cheap (I got mine for < $8) and easily acquired device which allows for the recording of rudimentary electrocardiograms. The kits often come with leads and a single set of pads, which is great for the first run, but afterwards you're gonna have to go out and buy some more pads (not expensive, but not super cheap). Each time you wish to take a recording, you then have to reapply the pads to the individual, wasting a disposable part each time. Solution This simple, 100% 3D printed part is my solution. It's a holder for the EKG leads which allows you to easily take a recording in no time! Simply: Print the part Insert the leads into their respective slots (each cable has different colors, make sure to correctly orient theleft andright arm leads in their respective slotson the top, and place theleg lead into the single slot on the bottom. Take your measurement by doing the following: 3.1. Place the device across theleft leg, with the single electrode facing down and pressing against bare skin (if you have hairy legs like mine, you can use an electrolyte pad as described below). 3.2. Place each thumb on its respective electrode on the top. 3.3. Wait a few seconds for the signal to stabilize, and you are ready to measure! How to create an electrolyte pad If you are having a hard time getting a good reading, you can try and improve the measured signal by creating an electrolyte pad to improve conductivity between your skin and the electrode. The leg lead has given me the most trouble, but you can quickly create a pad for all 3 leads. It's easy! Tear off a small strip of paper towel, fold it over 3-4x until it is a square which is just a bit larger than the metal contact of electrode. Quickly run the pads of paper towel under the sink to thoroughly soak them Pour a decent bit of regular table salt over the pads, allowing it to dissolve in the water Place the pad on your leg, on top of the electrodes, or you can even use the water to stick the pad to the 3D printed device!
