THE EEG-READY™ HELMET
Physip, a leader in EEG analysis for the research field, has been teaming up with industrial partners to deliver solutions that build on its experience in interpreting brain signal, and adapting it to specific industrial scenarios.
Sensors are directly integrated in head gear already in use today in a professional setting, transforming hard-hats currently used on construction sites, pilots headsets or military helmets, and turning them into EEG ready equipment.
Physip technology enables a reliable analysis of EEG signal, using 3 sensors only: a Cz sensor, located on top of the skull, on the median line connecting the nose to the back of the neck, a Pz sensor that serves as a reference point (REF), positioned about 8.5 centimeters behind the Cz sensor, and a ground electrode GND.
Sensors can be integrated into industrial hard hats, by clipping them onto the straps holding the helmet in place. Once the sensors have been affixed, the hard hat shell can be put back in place.
For audio headsets, EEG sensors are clipped on a reverse Y-shaped elastic strap, held in place using velcro. The Cz sensor is affixed right under the headset arch, and the Pz sensor behind it. The 2 Y branches of the strap are tied to the loudspeakers from behind,and support the ground electrode, while preventing undesirable lateral movement.
The military helmet displayed below is padded with a layer of protective foam. EEG sensors are clipped directly into the foam, in spaces carved out to accomodate them. Once the sensors are installed, the foam can be put back in place inside the helmet protective shell. All the wiring is on the outer surface of the padding, between the foam and the shell.
The helmet can then be connected directly to an EEG amplifier.
The helmet displayed above uses active EEG sensors Brain Products. Other sensors can be used as well, by simply adapting the material supporting EEG sensors that is inserted in the head gear.
