Embodiment 1

[0048]This embodiment discloses a wearable device for extracranial EEG sensing detection, which can relocate the sensor sites according to the position of the brain function area to be detected and according to the specific shape of the tester's skull, using fewer sensor layouts, so as to Accurate and flexible EEG information detection for different EEG regions of interest.

[0049] See attached figure 1 As shown, the specific structure includes:

[0050] Multi-longitude webbing with a certain degree of elasticity; Multi-dimensional webbing with a certain degree of elasticity; metal fixing nuts for the webbing; two fixed discs at the ears for tensioning the dimension webbing (disc peripheral bands Including fixing holes); the longitude sideband and the dimension sideband can use elastic plastic sidebands with sufficient length, the forehead position fixed sidebands need rigid plastic belts, the fixing nuts are plastic cylinders with the same caliber and length, and the single...

Abstract

The invention discloses a wearing device and method for sensor detection of extracranial electroencephalogram. The device comprises a plurality of longitudinal sidebands, a plurality of dimensional sidebands and two fixing discs, wherein the two fixing discs are used for tensioning the dimensional sidebands and are positioned at the ears of a person to be tested; a plurality of the longitudinal sidebands are respectively fixed on an inelastic longitudinal sideband fixing sideband at the forehead position; a plurality of latitudinal sidebands are respectively fixed on the preliminarily-fixed longitudinal sidebands; a sensor detection site is fixed on the longitudinal sidebands or the latitudinal sidebands; and coarse-grained adjustment is preformed on the sensor position based on the longitudinal sidebands or the dimensional sidebands and slight fine-grained adjustment is preformed on the sensor position based on fine holes on the longitudinal sidebands and the dimensional sidebands according to the functional area position of the interested electroencephalogram to be detected. A single sensor site can adjust the position thickness in the front and back (longitude), left and right (latitude) and two dimensions of the brain region.

Description

technical field [0001] The invention belongs to the field of EEG detection, in particular to a wearing device and method for extracranial EEG sensing detection. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] With the development of extracranial-oriented EEG wearable systems, it is necessary to flexibly detect EEG signals by using fewer EEG sensor detection sites for different detectors' skull shapes and different EEG regions. [0004] However, there are certain problems in the traditional extracranial EEG detection device, which are mainly reflected in: (1) the position of the sensor point of the detection device is fixed, and the position adjustment of the sensing detection point in different directions cannot be realized; (2) For the EEG area of ​​interest, a more flexible and targeted sensor layout solution is required; (3) Since the...
