It is important to apply a conductive cream (or water*) on the cardiac sensors or electrodes (bronze patches in the lining of the Shirt). Without any conductive agent, it becomes very difficult to record accurately any electrical activity on the surface of the skin and for you, to obtain reliable cardiac data.
As a conductive cream, you can use any glycerin-based cream. Before you start a recording session, you need to:
1. Put the shirt on carefully without stretching it too hard (for more details, refer to this link)
2. Roll up the lower part of the Shirt to expose the abdominal cardiac sensor electrode (bronze patch).
3. Apply a nickel-sized amount of your glycerin-based cream to the abdominal cardiac sensor. Do not rub the cream in the fabric.
4. Roll the lower part of the Shirt back down.
5. For the thoracic cardiac sensors, gently stretch the armpit opening on the right side of your Shirt until you are able to see one of the thoracic cardiac sensors.
6. Apply a nickel-sized amount of your glycerin-based cream to the cardiac sensor. Again, do not rub the cream in the fabric.
7. Repeat steps 5 and 6 for the other thoracic cardiac sensor.
8. Fasten the elastic belts.
You simply need to connect your Hexoskin Device then you are good to go!
* Note: keep in mind that if you are using water, you might have to re-moisten the cardiac sensors more frequently (every ~ 1-2 hours) than if you are using cream (every ~ 24 hours or whenever you take off your Shirt and put it back on). However, your sweat can replace the water if you perform intense physical activity.
