Electrodes, head-caps and sensors are designed to interface to almost any bioamplifier system, to the degree that the system conforms to some standard interface parameters. If you are looking for head caps, active electrodes, passive electrodes or other types of sensors that can be used with an existing system, chances are you are in the right place. Sensors that are designed only for use with a given acquisition system are listed as accessories under that system and are not duplicated here.
