The lowest energy state of a substance is that the solid is energized to become a liquid, and then to a gas. At this time, sufficient energy above the ionization energy is applied to the neutral gas, and ionization and recombination of electrons and ions can generate plasmas composed of electrons, ions, neutral atoms and molecules.

Inside this plasma, positive ions (ions) and negative charges (electrons) are mixed in almost the same amount and are called electrically ionized conductive gas paper because they maintain neutrality electrically while performing close to free grain Brownian motion.

Plasma is classified into plasma density, electron temperature, degree of thermal equilibrium between species, generation method and application field, but it is classified into density and electron temperature.

For example, the plasma may be classified into local thermal equilibrium (LTE) and non-local thermal equilibrium (non-LTE) by the degree of thermal equilibrium, and the term local heat equilibrium refers to the temperature Means the same thermodynamic state in the localized region of the plasma.

Plasma for research and manufacturing processes is usually one of LTE or non-LTE plasma, and the latter is generally called a thermal plasma and the latter is called a low-temperature plasma.

Atmospheric pressure plasma is mainly used in the fields of surface modification, coating, and environmental purification of materials.

In recent years, related research has been expanded to be applied to biomedical field and biomedical field. In the field of biomedical research, atmospheric plasma jet apparatuses have been studied extensively.

Here, the electrode structure of the plasma jet is mostly a needle-shaped electrode structure having various needle shapes, and various configurations have been studied depending on a power source device. Inert gas is mainly injected from the outside and a high voltage is applied to the needle electrode structure to generate plasma.

In addition, a dielectric barrier discharge (DBD) type plasma jet apparatus in which a small hole is formed in the center of a small circular parallel plate has been introduced.

Various kinds of plasma jet power supply devices are introduced according to the driving frequency, and a DC pulse power source and an AC power source are used as low frequency power supply devices of tens to hundreds of kHz.

In addition, plasma jets are widely used for sterilization and sterilization purposes. Plasma containing oxygen radicals have been studied for use in tooth whitening, pathogen destruction, blood coagulation, etc. Major issues in the utilization of the biomedical field include It is important to reduce the size, ease of control, and stability of the human body.

In addition, securing stability against electric shock is an important task for direct application to living cells or human body. Therefore, in order to ensure stability, high-voltage electrodes should not be in direct contact with the sample and the human body, and the driving voltage applied to the electrodes should be low, and the plasma current should be controlled to a small value of 1 to 2 mA, Should be.

And the minimum current that can be detected by the human body is about 1mA in the case of adult male at 60Hz commercial frequency alternating current, the sensing current should increase with increasing frequency, the current feeling in pain is 7 ~ 8mA, Not only electrical but also thermally dangerous.

Next, referring to conventional technologies using plasma, a technique for eradicating bacteria adhering to the face or skin using a light carbonized plasma in a portable beauty device using plasma (Korean Utility Model Application No. 2011-0003121) And the plasma skin regeneration device (Korean Patent No. 10-126232) has a technique for generating glow plasma and using it for skin treatment.

However, the portable beauty equipment and the plasma skin regenerating apparatus using the plasma have a problem that the plasma is directly transferred to the skin, thereby damaging the skin.

In addition, conventional portable beauty equipment and plasma skin regeneration apparatus using plasma have to inject gas for generating plasma, so that working time and work environment are limited and it is troublesome to charge or replace gas during operation.
