Abstract
A device for holding a measurement sensor perpendicular to the human head in which the sensor, such as a sponge EEG electrode, is incorporated within a pedestal tube (14) attached to a perpendicular pedestal collar (15) which is in turn attached to and positioned by a holding device, such as a the sensor positioning tension network (16) of my related invention, or an elastic cap. The distance of the pedestal collar, and thus the holding device, from the head can be adjusted, such as with a lock ring (17), such that only the foot of the sensor pedestal (18) enters the hair. The flared shape of the foot of the sensor pedestal acts to part and lift the hair during application, allowing the sensor pedestal tube, and in this embodiment the sponge of the EEG electrode (13), to rest directly on the scalp.
