Description of the drawings:

fig. 1 is a schematic structural view of an electrical impedance detection bracelet for gesture recognition according to the present invention.

Fig. 2 is a schematic structural view of the flexible bracelet bandage in fig. 1.

Fig. 3 is a schematic structural diagram of the electrode sheet in fig. 1.

The specific implementation mode is as follows:

the invention will be further described with reference to the accompanying drawings.

The electrical impedance detection bracelet for gesture recognition comprises a flexible bracelet bandage 1, an electrode plate 2 and an electrode plate fastener 3. A plurality of through-holes 4 have been seted up on flexible bracelet bandage 1, and electrode slice 2 installs and wears to locate in through-hole 4. Electrode slice 2 is provided with screw hole 6 including being located the inboard contact site 10 of flexible bracelet bandage 1 and wearing to locate in through-hole 4 and extending to the connecting portion 11 in the 1 outside of flexible bracelet bandage, in the connecting portion 11, electrode slice fastener 3 screws up and installs in screw hole 6 and then fix electrode slice 2 on flexible bracelet bandage 1. The contact portion 10 is formed with a groove 5 formed by a vertical and horizontal protruding prick, and the groove 5 is filled with conductive paste.

When the impedance detection bracelet for gesture recognition is used, the electrode plate 2 is connected with the thread of the threaded hole 6 through the electrode plate fastener 3, so that the electrode plate 2 can be fixedly connected to the flexible bracelet bandage 1, and the flexible bracelet bandage 1 is tightly attached to the electrode plate 2 and the skin through the elasticity of the flexible bracelet bandage, so that the contact impedance is reduced. And then coating the conductive paste in the groove 5 to ensure that the contact between the electrode plate 2 and the skin is good, and measuring the contact impedance.

The foregoing is only a preferred embodiment of this invention and it should be noted that modifications can be made by those skilled in the art without departing from the principle of the invention and these modifications should also be considered as the protection scope of the invention.
