 FlexTrodestm
US Patent NO. 6,574,513
FLEXTRODES
consist of a hollow, screw-like plastic retainer containing a felt
wrapper that encloses a standard gold cup electrode. They are
used with a retaining ring that can be inserted in a headband, hat,
or other holder. This provides a simple, clean, self-abrading
and self-cleaning, paste-free and gel-free contact. Used for
EEG, EMG, EKG and related body potential recording. Ideal in cases
where it is difficult to get a good connection, especially through
hair. Electrode lead color our choice. Easy to apply and remove B
leaves hair clean without a trace of goo! A must in keeping
teenagers and adults happy to come back! (see
also “What are Flextrodes)

What
Are Flextrodes
FlexTrodes
(US
Patent NO. 6,574,513)
are simple, clean, self-abrading and self-cleaning, paste-free and
gel-free electrodes. They are intended for EEG, EMG, EKG, and
related body potential recording work. They are suitable for use to
contact and record biopotentials from the head, face, and other body
areas. They are especially useful in cases where it is difficult to
get a good connection through the hair, and where chemicals, gels,
or pastes are undesirable.
What
can I do with them?
FlexTrodes can be used with the BrainMaster recording modules, or
with similar instruments such as the WaveRider, BrainTracer, Mind
Mirror, POD, and so forth. They can also be used with any
physiological instrumentation that expects a conventional,
metal/saline type of electrode, with a secure connection to the
head, face, or other body area. FlexTrodes can be used in
combination with other electrodes, providing maximum flexibility.
What
do they consist of?
Each consists of an adjustable plastic holder, a contact surface, a
sponge matrix, and an embedded electrode of gold, silver,
stainless-steel, or tin. This assembly fits into a retaining ring
that can be affixed to a headband, hat, or other device. The
electrolyte is included. The electrode itself is of a typical
commercial variety.
NOTE:
FlexTrodes are not approved for clinical use, and no such claims are
made.
Instructions
for Use:
FlexTrodes are used to obtain a clean, wet, physically secure
electrical connection to the skin. If the connection is to be made
to the scalp, it is necessary to either wet the hair beneath the
electrode, to part the hair beneath the electrode, or both.
FlexTrodes
are used in one of two ways:
| |
 |
By
putting on the headset or supporting gear first, preparing
the surface, and then inserting the electrode, and |
| |
|
By
first installing the electrode into the headset or
supporting gear, and then putting the entire assembly in
place. Which of these you use depends on the specific
situation. Also, once the electrodes are put in place, it is
possible to remove and reinsert them as needed, to ensure
best contact. It is also possible to add more electrolyte
once the electrodes are in place, to maintain good
electrical contact. |
For
best contact, observe the following:
| |
|
Ensure
that the contact surface is clean, and essentially free of
layers of hair. |
| |
|
Move
or part the hair, to give the electrode access to contact
the scalp. |
| |
|
Moisten
the contact surface. Use the squirt bottle, and/or a Q-tip,
if desired. |
| |
|
Rub
or clean the skin surface, if you experience contact
difficulties. Electrode prep gel is generally unnecessary,
but can be used if desired. |
| |
|
Insert
the electrode until the sponge or pad securely touches the
skin. |
| |
|
Add
electrolyte fluid as needed, to maintain a moist, electrical
contact. |
Instructions
for Storage and Reuse:
For
convenience, FlexTrodes can be stored in the conductive solution,
leaving them ready for reuse at any time. In addition, this helps to
keep the electrode surface stable. The electrodes can be removed
from the headband or support, and kept in a plastic film container,
with the electrode wire protruding under the lid. To protect this
wire, it is best to cut a small notch in the lid, and in the can
rim, to avoid putting undue pressure on the lead wire. FlexTrodes
are supplied packaged in this type of container. The container can
be filled ½ way with the same electrolyte prepared for use with
them, and electrodes can be stored in this fashion.
