Description

[0001] The present invention relates to a human potential measuring device,

TECHNICAL FIELD The present invention relates to an apparatus for measuring a potential of a human body, and more particularly, to a human potential measuring apparatus for measuring a potential of a human body charged by electrostatic induction.

In the space where most of daily life such as residential space and office space of modern society is performed, electromagnetic fields of large and small are formed by various electronic products and electric power networks. These electromagnetic fields generated by electronic products are generally adjusted to minimize the influence on the human body within a certain level, but they can not completely prevent the human body from being affected by electromagnetic fields formed by various electronic devices and power networks. As a result, the body in this space is always placed in a somewhat electrostatic induced state, i.e., in an electrically charged state, which can lead to physiological imbalance and disease. Therefore, a technique for an apparatus for electrically grounding a human body in such a space or for measuring the amount of electric current charged to the human body by electrostatic induction has been disclosed.

The products to which such a technology is applied can be applied to a chair, a cushion, a rug, and the like, in which a user's physical contact frequently occurs in a daily living space.

However, such grounding appliances are relatively expensive compared to products that are not grounded, and thus are not applicable to all products in a residential environment, and are preferably selectively applied where major body contact occurs. In particular, a grounding product may be installed in a place where a strong electromagnetic field is generated in the residential space and electrostatic induction occurs in the human body.

Therefore, a potential measuring device for measuring the space where electromagnetic fields mainly occur may be required. Generally, a tester can be used to measure the voltage of the micro current charged to the human body. However, the tester used for the electric equipment construction and the electric appliance test is relatively expensive and difficult to operate, .

In order to solve the above-described problems, the present invention provides a human potential measuring apparatus which can measure a micro current charged in a body in a usual residential space, thereby providing an appropriate grounding means.
