Electrode Skin Preparation Tutorial

BITalino and biosignalsplux electrophysiology sensors require the use of sensor electrodes, which are available as dry electrodes or pre-gelled & self-adhesive electrodes.

If you are new to electrode-based sensor acquisitions, we recommend starting with the pre-gelled electrodes and following the step-by-step instructions below to ensure correct skin preparation & electrode placement.

This guide is compatible with the following BITalino & biosignalsplux sensors:

We recommend also consulting the BITalino Sensor Documentation and biosignalsplux Sensor Documentation for further sensor-specific electrode placement instructions.

Skin Preparation for Pre-Gelled Electrodes

By following these steps, you can properly apply pre-gelled electrodes for electrophysiology sensors to ensure accurate and reliable readings.

Pre-gelled electrodes do not require the application of additional conductive gel or paste, as the electrodes are already coated with a conductive gel. However, it is important to clean the electrodes and shave any hair from the area where they will be placed to ensure good contact between the electrodes and the skin.

  1. Clean the skin: Use a mild soap and water to clean the area of the skin where the electrodes will be placed. Be sure to thoroughly rinse off any soap and dry the skin with a clean towel. Alternatively, you can also use the NuPrep Skin Preparation gel.
  2. Shave any hair: If necessary, use a razor or other hair removal method to shave any hair from the area where the electrodes will be placed. This will ensure good contact between the electrodes and the skin.
  3. Connect the electrodes to the sensor: Connect your sensor to your electrode
  4. Place the electrodes: Remove the protective cover from the electrode and gently place the electrodes on the skin, making sure to follow the manufacturer’s instructions for proper placement.

Skin Preparation for Dry Electrodes

By following these steps, you can properly prepare the skin and apply electrodes for electrophysiology sensors to ensure accurate and reliable readings.

  1. Clean the skin: Use a mild soap and water to clean the area of the skin where the electrodes will be placed. Be sure to thoroughly rinse off any soap and dry the skin with a clean towel. Alternatively, you can also use the NuPrep Skin Preparation gel.
  2. Shave any hair: If necessary, use a razor or other hair removal method to shave any hair from the area where the electrodes will be placed. This will ensure good contact between the electrodes and the skin.
  3. Clean the electrodes: Before applying the electrodes, clean them with alcohol or an electrode cleaning solution to remove any dirt or oil.
  4. Connect the electrodes to the sensor: Connect your sensor to your electrode
  5. Apply conductive gel or paste: Apply a small amount of conductive gel or paste (e.g. Ten20 Conductive Paste) to the electrodes to help improve the conductivity between the electrodes and the skin.
  6. Place the electrodes: Gently place the electrodes on the skin, making sure to follow the manufacturer’s instructions for proper placement.
  7. Secure the electrodes: Use medical tape or other adhesive to secure the electrodes in place, making sure that they are not too tight or too loose.
