Eeg Cap Maintenance - MBT SMARTING 24 User Manual

11. EEG Cap Maintenance

Although not an integral part of SMARTING system, it is important to note
that, especially within the scope of EEG applications, it is crucial to perform
proper recording cap maintenance. Acting contrary might induce e.g. high
impedance values and disrupt experiments.
We provide short instruction on the maintenance procedure on the example
of EasyCap solution:
This EEG Cap contains Silver-Silver Chloride (Ag/AgCl) electrodes. Corrosive
substances will damage the electrode. These electrodes should not come into
direct contact with metals in order to avoid corrosion. It is extremely
necessary to clean the electrodes immediately after the measurements are
performed and then let them dry. Rinse the gel by using warm water, but in
the same time make sure that you keep the connector dry. If the electrodes
absorb the gel (by i.e. not being cleaned properly), it will speed up the
process of corrosion and make the measurements contain more noise.
Afterwards, dry the cap with a towel and hang it to dry completely before
taking any other measurements.
The cap should not be stored with metal in such a way that the electrodes
touch metal. The cap should be stored in a clean, dry and dark container,
such as plastic or glass.
