Abstract
The present invention relates to a human insertion type probe apparatus.

Description
The present invention relates to a human insertion type probe apparatus.
Surface Electrode has advantages of being universally used and easily handled due to its non-invasive characteristics. However, the simple metal surface electrode according to the prior art has a high impedance in sensing or stimulating a biological signal, There is a problem in that it is difficult to make a meaningful sense since the rain does not become large.
In addition, the simple metal surface electrode according to the related art has a problem that power consumption at the time of stimulation increases, and damage to the brain or body organs may occur.
In addition, the simple metal surface electrode according to the prior art has a problem in that the flexibility is poor, and the electrodes are disconnected at the time of surgery, and the external connection portion is disconnected after inserting into the human body.
SUMMARY OF THE INVENTION It is an object of the present invention to provide a flexible human insertion type probe device which enhances the surface area and the adhesive force and secures biostability and operational reliability.
The flexible human body-inserted probe device according to one aspect of the present invention includes a nano-structure including a planar composite electrode which is supplied with power from the outside and is manufactured and bent in a flexible structure, .
The flexible human implantable probe device according to the present invention has the effect of enhancing the surface area and the adhesive force by using the nanowire or nanotube structure.
In addition, the nanostructure has an effect of enhancing biostability by surface-treating the surface of the nanostructure using a biocompatible conductive organic material.
In addition, the drug which increases the wound stability between the nanostructures is stored, and the drug stored by using the capillary phenomenon is secreted little by little, thereby increasing the biostability.
In addition, it is possible to secure flexibility and high conductivity by using a flexible nano material, a conductive 2D material and a metal film, and it is possible to prevent a disconnection when the electrode is bent, thereby securing operational reliability.
In addition, since the nanostructure ultimately coats the conductive organic material on the surface thereof, it maximizes the surface electrode and facilitates the ion transfer, thereby ensuring low impedance and increasing the ratio of signal to noise, thereby securing the sensing reliability.
The effects of the present invention are not limited to those mentioned above, and other effects not mentioned can be clearly understood by those skilled in the art from the following description.
