EMG Electrode Conductive Gel

Conductive gel is extremely useful when you use electrodes to record electrical activity on the surface of your skin. The outside layer of skin you see everyday in the mirror is really made up of dead skin cells. These skin cells act as a good resistor, meaning that it makes detecting electrical activity difficult for your EMG electrodes. So how do you solve this problem? You need a good conductor!

Enter Conductive Electrode Gel...

Conductive Gel is usually viscous and salty, this acts as a conductive liquid medium to put between your skin and the electrode. In other words, the gel helps your electrode detect the electrical activity under your skin. So how do you procure or make electrode gel? It's easy and you have several good options available:

1) Spectra 360 Electrode Gel for $10.00: This conductive gel is hypoallergenic and is the brand we personally use for research and demonstrations.

2) 100 Vermed Electrodes for $29.99 These electrode patches are the same ones we provide with our EMG SpikerBox. Each electrode patch contains conductive gel built in. Like the Spectra 360 Electrode gel, they are hypoallergenic as well.

3) Lastly, you can easily make your own electrode gel. You will need:

  • A plastic resealable bag.
  • Some aloe vera gel.
  • Table salt.


Take 100 mL of the aloe vera and place it in the resealable bag. Next take about 20 grams (or 1 tablespoon) of salt and add it to the aloe vera. Seal the plastic bag and begin to mash and mix the gel and salt. Once the salt has completely dissolved you will be ready to use your new conductive gel. Using a Q-Tip, try applying a small amount gel to the part of the brass popsicle stick electrode that touches your skin.
