[0026] The deficiencies of the prior art are the results of the inventors after practice and careful study, and therefore the discovery process of the above problems and the solutions proposed by the present disclosure to the above problems should be the contributions of the inventors to the present disclosure in the process of the present disclosure.
[0027] As shown in Figure 1 , 2 , 3, 4, the present disclosure provides a physiological signal acquisition elastic band, comprising: a first elastic structure layer, a second elastic structure layer, an electrode lead wire 3, and a plurality of electrodes 4; the first elastic structure layer and the second elastic structure layer each comprise an elastic fabric layer 1 and a sponge layer 2, and the elastic fabric layer is located on the outside in use; the electrode lead wire is located between the first elastic structure layer and the second elastic structure layer, and the electrode is exposed to the second elastic structure layer and connected with the electrode lead wire. Wherein, the electrode can be used to collect electroencephalogram information and / or electromyogram information of a target object. Wherein, the elastic fabric layer 1 and the sponge layer 2 can be hot-pressed to obtain the first elastic structure layer and the second elastic structure layer by hot-pressing molding.
[0028] The present disclosure provides a physiological signal acquisition elastic band, both of the two elastic structure layers of the physiological signal acquisition elastic band comprise a sponge layer, the sponge layer has a certain degree of elasticity, which can reduce the discomfort caused by wearing, thereby reducing the influence on the sleep of the collection object as much as possible.
[0029] The present disclosure provides a possible implementation, specifically, the sponge layer has a certain strength, and the longitudinal section of the first elastic structure layer and the second elastic structure layer is trapezoidal or arc-shaped, so that the physiological signal acquisition elastic band can be stably worn on the head of the target object in use. Wherein, the opening of the trapezoidal or arc-shaped can be slightly smaller than the head circumference of a person, so that the physiological signal acquisition elastic band can form effective contact with the target object and have a certain contact pressure, thereby being stably worn on the head of the target object.
[0030] In the present disclosure, the sponge layer has a certain strength, and through the cooperation of the sponge layer and the elastic fabric layer, the longitudinal section of the first elastic structure layer and the second elastic structure layer is trapezoidal (as shown in Figure 1 ) or arc-shaped, so that the physiological signal acquisition elastic band can be stably worn on the head of the target object in use. In addition, the arc-shaped or trapezoidal design with elasticity also increases the adaptability of the physiological signal acquisition elastic band, which can adapt to target objects with different head circumferences.
[0031] The second elastic structure layer includes an electrode arrangement area 5, which is a cuboid or a cube. The electrode arrangement area can be configured with different numbers of electrodes according to the needs of the collection area. For example, if the top of the head area is collected, four electrodes can be configured, and if the back of the head area is collected, two electrodes can be configured.
[0032] The second elastic structure layer includes an electrode arrangement area 5, which is a cuboid or a cube. The electrode arrangement area can be configured with different numbers of electrodes according to the needs of the collection area. For example, if the top of the head area is collected, four electrodes can be configured, and if the back of the head area is collected, two electrodes can be configured.

[0035] The two ends of the physiological signal collection elastic band are respectively connected to the two sides of the top area inside the head-mounted device, for collecting physiological signal information of the parietal lobe area of the target object. The electrode is a claw-shaped soft rubber electrode. Therefore, since the claw-shaped soft rubber electrode has a certain flexibility, the design of the first elastic structure layer and the second elastic structure layer including the sponge layer further reduces the discomfort caused by wearing, so that it can be used during sleep, and minimizes the discomfort caused to the measurement object. In addition, the claw-shaped soft rubber electrode can effectively pass through the hair area on the top of the head, thereby collecting physiological signal information of the parietal lobe area of the target object.
