Material for doing electrode is conductive rubber.In addition, sheet metal, conductive fabric etc. in principle can also be used as electrodes.Wherein, metal
Piece is inextensible, and very poor with the stickiness of skin, and part metals are also easy to get rusty, so being not suitable for directly as electrode contact
Skin；Conductive fabric is good with the stickiness of skin, and extensibility is relevant with weaving manner, can have good extensibility, but its fiber
The metallic particles of outer layer is easily washed off through repeatedly washing, so nor being especially suitable as electrode；Conductive rubber slice has one
Fixed extensibility, but requirement is typically also can not meet, and also after stretching, its resistance can be significantly increased, doping metals particle fraction
Larger conductive rubber even can lose electric conductivity, so existing conductive rubber slice is directly used as electrode and does not play stretching for it
Malleability.
The content of the invention
Present invention solves the technical problem that be, the electrode used by the instrument of existing detection electrocardiosignal or electromyographic signal is not
The conductive material for possessing extensibility or possessing extensibility there is also electric conductivity decline or short-life problem.
In order to solve the above problems, the present invention provides a kind of extensile flexible electrode, island bridge of the electrode for hollow out
The conductive rubber slice of structure, bridge is shaped form, and bridge width is close with thickness.
Further, the island bridge construction is periodic arrangement.
Further, a face contact human body skin of the electrode, for detecting electrocardiosignal or electromyographic signal, another side
Marginal portion by conductive adhesive sheet metal, lead is picked out again by sheet metal, for being connected to external circuit.
Further, elastic packing of the electrode with preferable mobility, high fracture extension rate, low elastic modulus and soft
The blank space of glue filling engraved structure and encapsulation.
Further, the processing mode of the hollow out is high-precision machine cuts or laser cutting.
The present invention also provides a kind of preparation method of extensile flexible electrode, comprises the steps：
A) hollow out processing is carried out to conductive rubber slice using high-precision machine cuts or laser cutting mode so as to have
Island bridge construction；
B) with conducting resinl by a face of hollow out conductive rubber slice and the metal bonding film with lead, in order to keep stretching
Property, a die area at a bonding conductive rubber slice edge；
C) with the elastic sealant filling hollow out knot of preferable mobility, high fracture extension rate, low elastic modulus and soft
The blank space of structure and encapsulation.
Further, the step c) is specially：
1) by after hollow out and the conductive rubber slice of bonded metal piece is inserted in uncovered cuboid container, conductive rubber slice is not
That face hydrosol of bonded metal piece is pasted onto on the inner bottom surface of container, and other inwalls of container will also be coated water-soluble
Glue, waits water-soluble adhesive curing；
2) again by the elastic sealant injection container of preferable mobility, high fracture extension rate, low elastic modulus and soft
In；
3) container is stood into a period of time, again container is steeped after waiting elastic sealant solidification and make in water water-soluble peptization
Change, then directly take out flexible electrode.
Present invention technique effect compared with prior art：
Comparing and directly conductive rubber slice being used as electrode, the method for the present invention significantly increases its extensibility and keeps
Good electric conductivity.
Compare using sheet metal as electrode, the method for the present invention has good extensibility and stickiness, and will not
Get rusty.
Compare using conductive fabric as electrode, the method for the present invention has higher service life.
