Description
The present invention relates to a micro needle electrode patch and a manufacturing method thereof, and more particularly, to a micro needle electrode patch including a through electrode and a manufacturing method thereof.
The medical electrode is generally a device for sensing a human body signal or stimulating a human body, and may be a converter for converting a biological signal into an electrical signal. Such a medical electrode can be broadly divided into a non-invasive electrode and an invasive electrode. The non-invasive electrode is an electrode capable of measuring an extracorporeal bio-signal by adhering it to the skin without penetrating the electrode, because the adhesive is formed on the electrode surface together with the sponge carrying the electrolyte solution or the electrolyte solution. An invasive electrode is an electrode that invades a needle skin, and a needle-shaped electrode penetrates the skin to measure a biological signal in the body. The invasive electrode has an advantage of measuring a more precise living body signal as compared with a non-invasive electrode.
However, in the case of an invasive electrode, it is possible to measure the biological signal more precisely than the non-invasive electrode, but the convenience is poor and the patient has to suffer pain. In addition, when electrical stimulation is added using a conventional abdominal electrode, if the area of contact with the skin is small, the resistance is reduced and the patient suffered a severe pain. Therefore, there is a need to develop an invasive electrode capable of efficiently measuring a biological signal or adding electrical stimulation while generating a low level of pain.
It is an object of the present invention to provide a micro needle electrode patch capable of efficiently measuring a biological signal or adding electrical stimulation to a low level of pain and tissue damage.
Another object of the present invention is to provide a method of manufacturing the micro needle electrode patch.
A microneedle electrode patch for an object of the present invention includes a patch layer having a plurality of microneedles formed on one surface thereof, a conductive penetrating portion disposed on the one surface of the patch layer through the patch layer and disposed with the microneedles, And a conductive layer formed on one side of the patch layer and in contact with the micro needle and the conductive penetration part, And a metal layer connected to the electrode portion through the penetrating portion so as to be in electrical communication with the electrode portion.
In one embodiment, the micro needle electrode patch may be for bioelectrical potential measurement or bioelectrical stimulation.
At this time, the living body potential may include at least one of ECG, Electrocardiogram, EMG, Electroencephalogram (EEG), and Electrogenogram (ENG).
In one embodiment, the conductive penetration may be needle-shaped.
At this time, the protruding height of the conductive penetrating portion penetrating through the patch layer may be less than the protruding height of the micro needle at one side of the patch layer.
In one embodiment, the metal layer is formed on one side of the patch layer, and may cover the entirety of a plurality of micro needles formed on one side of the patch layer and a conductive penetration surface through the patch layer.
At this time, the metal layer may be formed of at least one of gold, silver, platinum, and titanium.
In one embodiment, the patch layer may be formed of a polymeric compound.
In one embodiment, the penetrating electrode may be formed of a metal containing at least one of gold, silver, platinum, and titanium.
In one embodiment, the penetrating electrode further includes a flat portion formed between the conductive penetrating portion and the electrode portion, and the flat portion can contact the opposite surface of the patch layer where the electrode portion is disposed.
At this time, the area of the flat portion may be wider than the through hole area of the patch layer through the conductive penetrating portion.
Another aspect of the present invention is a method for manufacturing a micro needle electrode patch, the method comprising the steps of: inserting a penetrating electrode including a conductive penetrating portion and an electrode portion connected to the conductive penetrating portion into a patch layer having a plurality of micro- And forming a metal layer on one side of the patch layer having the electrode inserted thereon so as to contact the micro needle and the conductive penetration portion.
In one embodiment, the step of inserting the penetrating electrode may include inserting the penetrating electrode toward the one surface from the opposite surface of the patch layer, the penetrating electrode penetrating the patch layer, And the electrode portion of the penetrating electrode may be disposed on the opposite surface of the one surface.
In one embodiment, the method of fabricating the microneedle electrode patch further comprises forming a patch layer having a plurality of microneedles formed on one side thereof before inserting the penetrating electrode, And a polymer compound is added to a mold including an engraved pattern having the same shape as that of the mold.
The step of inserting the penetrating electrode may include inserting the penetrating electrode in a state where the patch layer is not cured, curing the uncured patch layer into which the penetrating electrode is inserted, And removing the inserted patch layer from the mold.
According to the microneedle electrode patch of the present invention and the manufacturing method thereof, it is possible to provide a microneedle electrode patch with improved limitations of the irrigation type electrode and the non-invasive type electrode. The microneedle electrode patch of the present invention includes a plurality of microneedles, which can cause a low level of pain and tissue damage due to the minimal invasion through the stratum corneum of the skin with a wider contact area. In addition, the micro needle electrode patch of the present invention can precisely and efficiently measure biological signals or add electrical stimulation and can be used easily.
