Fig. 1 is the structural representation of the shape-variable surface myoelectric electrode of the present invention.Fig. 2 is this hair
The internal structure schematic diagram of bright shape-variable surface myoelectric electrode.It is shown as depicted in figs. 1 and 2,
Shape-variable surface myoelectric electrode includes：Electrode capsule 11, support is arranged on the inside of electrode capsule,
Electrode capsule is propped up from inside, the part that the electrode capsule front end propped up is contacted with skin is electrode detection area
Domain.
Electrode capsule 11, is made up of soft material, and the electrode detection region of electrode capsule 11 is evenly distributed with
Multiple surface electrodes 12.
Support, including support ring and pulling unit.
As shown in Fig. 2 support ring is alternately connected by multiple support chips 14 of first support chip 13 and second
Formed, be to rotate connection between the first support chip 13 and the second support chip 14.In this embodiment party
In formula, there are four the first support chips 13 and four the second support chips 14.
Pull unit that there is stator 15, bracing wire 16 and stepper motor 17, stator 15 is fixed
In the junction of the first support chip 13 and the second support chip 14, stator 15 is flexible, two
Adaptability occurs accordingly for the shape of stator 15 when variant occurs for the angle between individual support chip
Change.Bracing wire 16 is connected between two relative stators 15, and each bracing wire is kept when static
Tensioning state, to maintain the shape of support ring.Stepper motor 17 is connected to the centre of bracing wire 16,
Bracing wire is pulled back and loosening operation.The scrolling wiring of stepper motor 17 is to adjust the length of bracing wire 16
Degree, so as to change the shape of support ring, and then makes the shape in the electrode detection region of the front end of electrode capsule 11
Shape changes.When shape-variable surface myoelectric electrode needs to change shape, with the institute from Fig. 2
