FlexTrodes

What are they?

FlexTrodes 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, Spectrum Cybernetics, EEG Pathways (Dr. Ayres), Lexicor, 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 a hollow, screw-like plastic retainer containing a felt wrapper that encloses a standard gold cup electrode. It is used with a retaining ring that can be inserted into a headband, hat, or other holder. This provides a simple, clean, self-abrading and self-cleaning, paste-free and gel-free contact.
