The contact between the leaf and the clip needs to be good enough to establish electrical conductivity between the two elements. Water is a very good conductor and can improve the contact. If “bad contact” appears on the device, make sure that the leaf is sufficiently moistened. You can use our gel available in our online shop.

When you put in contact two different elements a third layer is created in between the two made of dust, dead cells, microbubbles of air, pores. To have an excellent connecting interface you can use water that can adjust the different irregularities and increase conductivity.
