Referring to fig. 3, two or more support bars 5 are arranged in the conductive layer 3 at intervals along the length direction, the support bars 5 protrude downward from the conductive layer 3, two or more microelectrodes 6 are distributed on the lower surface of the conductive layer 3, and the height of the downward protruding parts of the support bars 5 is greater than that of the microelectrodes 6. Wherein the micro-electrode 6 comprises nano-metal particles or nano-conductive fibers. Of course, other microelectrodes 6 in the nanometer size range may be used by those skilled in the art, and the present invention is not limited thereto.
When the electronic bandage of the embodiment of the present invention is used to wrap a wound, the downward protruding portions of the supporting bars 5 of the electronic bandage will contact the surface of the injured skin and form an electric field space between the micro-electrodes 6 and the surface of the injured skin. After power-on, the negative high voltage generated by the negative high voltage generator 4 will be applied to the micro-electrodes 6 through the conductive layer 3. Under the action of negative high voltage, the microelectrode 6 can ionize air in the electric field space to generate negative ions, and the negative ions migrate to the surface of the injured skin under the action of the electric field. Because the negative ions have the bactericidal effect, the wound infection can be prevented after the negative ions migrate to the surface of the injured skin, so that the anti-inflammatory drug does not need to be smeared on the surface of the wound regularly, and the drug resistance of a human body cannot be generated.
As a preferable mode, two or more micro-electrodes 6 are uniformly distributed on the lower surface of the conductive layer 3. Thereby making the process of generating negative ions more controllable.
According to the formula of the electric field intensity: and E is the electric field intensity between the two polar plates, U is the voltage between the two polar plates, and d is the distance between the two polar plates. In the embodiment of the present invention, in order to adjust the concentration of the negative ions ionized in the air between the micro-electrode 6 and the surface of the injured skin, the following two ways are available.
In the first way, the concentration of the negative ions ionized in the air between the micro-electrode 6 and the surface of the injured skin can be adjusted by adjusting the distance between the micro-electrode 6 and the surface of the injured skin, that is, the distance from the end of the downward-projecting part of the supporting strip 5 of the electronic bandage to the end of the micro-electrode 6.
As an example, in order to enable negative ions to be radiated in the air between the micro-electrode 6 and the wounded skin surface, the distance S from the end of the downwardly protruding portion of the supporting bar 5 to the end of the micro-electrode 6 satisfies S0< S, wherein S0Is a minimum distance S between the end of the downward protruding portion of the supporting bar 5 and the end of the micro-electrode 6 capable of radiating negative ions0The calculation formula of (2) is as follows:
substituting formula (2) and formula (3) into formula (1) can yield S0Where i, j, k is a set of three-dimensional vectors, U0Electrode escape voltage of an electric field formed by the skin of the human body contacted by the microelectrodes 6 and the supporting bars 5, E0The electric field intensity of the electric field formed by the micro-electrodes 6 and the human skin.
As another example, in order to enable negative ions to be radiated from the air between the micro-electrode 6 and the surface of the damaged skin without breaking down the air between the micro-electrode 6 and the surface of the damaged skin, the distance S from the end of the downwardly protruding portion of the supporting bar 5 to the end of the micro-electrode 6 satisfies S0＜S＜S1Wherein S is0Is a minimum distance S between the end of the downward protruding portion of the supporting bar 5 and the end of the micro-electrode 6 capable of radiating negative ions1A minimum distance S between the end of the downward protruding portion of the supporting bar 5 and the end of the micro-electrode 6 capable of radiating negative ions without breaking down air1The calculation formula of (2) is as follows:
substituting equation (5) and equation (6) into equation (4) yields S1Where i, j, k is a set of three-dimensional vectors, UCAir breakdown voltage of electric field formed by the human skin in contact with the microelectrodes 6 and the supporting bars 5, E0The electric field intensity of the electric field formed by the micro-electrodes 6 and the human skin.
In the second mode, the concentration of the negative ions ionized in the air between the microelectrode 6 and the injured skin surface can be adjusted by adjusting the voltage between the microelectrode 6 and the injured skin surface, i.e. the negative high voltage applied to the microelectrode 6 by the negative high voltage generator 4.
By way of example, the concentration of the negative ions ionized in the air between the microelectrodes 6 and the surface of the injured skin can be controlled by providing a voltage regulator 10 in the insulating layer 2, and adjusting the magnitude of the negative high voltage generated by the negative high voltage generator 4 by the voltage regulator 10.
As another example, referring to fig. 5, the electronic bandage further includes a voltage regulator 10 disposed in the insulating layer 2 and a bluetooth chip 11 of the voltage regulator 10 disposed in the insulating layer 2, the voltage regulator 10 and the bluetooth chip 11 are both connected to the power supply 9, and the voltage regulator 10 is further connected to the bluetooth chip 11 and the high voltage generator, respectively.
The bluetooth chip 11 is used for pairing with a migration device of a user, and after the pairing is successful, the user may send a user instruction of voltage increase or voltage decrease to the voltage regulator 10 of the electronic bandage through the associated client application 12. The voltage regulator 10 receives a user instruction through a Bluetooth chip 11 in the electronic bandage, correspondingly adjusts the magnitude of the negative high voltage generated by the negative high voltage generator 4, and further controls the concentration of the negative ions ionized in the air between the microelectrode 6 and the wounded skin surface.
Further, referring to fig. 6, the electronic bandage further includes a negative ion detector 13, the negative ion detector 13 is disposed on the protruding portion of the supporting strip 5, and the negative ion detector 13 is connected to the power supply 9 and the bluetooth chip 11, respectively.

Based on the detected negative ion concentration, the user issues a user instruction of voltage increase or voltage decrease.
In order to calculate the concentration of the negative ions ionized in the air between the micro-electrode 6 and the wounded skin surface, it can be assumed that each oxygen molecule acquires a free electron and becomes a negative oxygen ion, and the calculation formula of the concentration N of the negative ions is: where I is the current between the micro-electrode 6 and the wounded skin surface, and N is one unit.
According to an embodiment of the present invention, in the electric field between the microelectrode 6 and the wounded skin surface, the potential at infinity is zero for a negative high voltage on the microelectrode 6. In order to make the surface of the injured skin have zero potential so as to improve the concentration of negative ions ionized in the air between the microelectrode 6 and the surface of the injured skin, the electronic bandage further comprises a lead wire 8 connected with the human body, one end of the lead wire 8 is connected with the negative high-voltage generator 4, and the other end of the lead wire 8 penetrates through the braid 1 and extends outwards.
