Scheme is explained in detail and illustrated.
The embodiment of the present invention one provides a kind of liquid metal electrode based on hot gas driving, referring to Fig. 1, the liquid
Metal electrode, including：
Fluid reservoir 4, the fluid reservoir 4 is interior to include the first space and second space；First space is to connect with second space
Relation；
And
Air bag 3 positioned at the first space and the liquid metal 2 positioned at second space, the liquid metal 2 is positioned at described
Outside air bag 3；
The liquid metal electrode also includes：
Electrode nozzle 1 above fluid reservoir 4, wherein, the electrode nozzle 1 is particularly located at the upper of the second space
Side, the electrode nozzle 1 are the hollow pipeline in cone shape, including upper end tube nozzle and the lower end mouth of pipe, the lower end mouth of pipe with
The second space connection；The upper end tube nozzle is the working position of the liquid metal electrode, for example, with contact biological tissue
Position；
Temperature control chip 5 positioned at the bottom of fluid reservoir 4, one end of the temperature control chip 5 is stretched out outside the fluid reservoir 4, for connecting
Temperature control circuit；The temperature control chip 5 controls it to freeze and heat by additional temperature control circuit, therefore to control the volume of air bag 3.Separately
Outside, in order to improve control efficiency, the size of the temperature control chip 5 is identical with the size of the bottom surface of fluid reservoir 4；
Connecting wire 6, the first end of the connecting wire 6 are connected with the liquid metal 2, and the liquid storage is stretched out at the second end
Outdoor, for connecting power circuit.
Referring to Fig. 2 a, in the state of the liquid metal electrode is not used, temperature control chip 5 is not heated, and the volume of air bag 3 is in
Minimum state, liquid metal 2 are stayed in fluid reservoir 4；Referring to Fig. 2 b in the state of using the liquid metal electrode, pass through temperature control
Circuit control temperature control chip 5 heats, and the volumetric expansion of air bag 3, promotes liquid metal 2 to enter electrode nozzle 1 by fluid reservoir 4, finally exists
The upper end tube nozzle of electrode nozzle 1 forms circular electrode interface.Wherein, the circular electrode formed in the upper end tube nozzle of electrode nozzle 1
Contact surface, have well-regulated shape and smooth interface, be advantageous to the uniform release of electric charge, thus with more stable electricity thorn
Swash effect.
After use terminates, temperature control chip 5 is controlled to freeze or stop heating, the volume contraction of air bag 3, liquid by temperature control circuit
Metal 2 is come back in fluid reservoir 4, realizes the separation of electrode and biological tissue.Now in order to save electric energy, should stop to described
Connecting wire 6 is powered.
It can be seen that electrode of the liquid metal 2 as release electrical stimulation signal, when discharging electro photoluminescence, liquid metal 2 enters electricity
