Abstract

An earthing mat and a method for manufacturing the same are provided. The earthing mat comprises a lower sheet layer in contact with a floor surface, a fiber layer composed of a plurality of yarns fixed in a direction intersecting the lower sheet layer, and an upper sheet layer laminated on the fiber layer and in contact with a user, thereby providing grounding to the user. The cushioning and usability are improved, and the mat can be easily washed.

Description

Earthing mat with improved usability, and method of manufacturing the same The present application relates to an earthing mat, and more specifically, to an earthing mat comprising a lower sheet layer in contact with a floor surface, a fiber layer composed of a plurality of yarns fixed in a direction intersecting the lower sheet layer, and an upper sheet layer laminated on the fiber layer and in contact with a user, which provides grounding to the user, is easy to wash, and has an improved user experience, and a method for manufacturing the same. Generally, earthing refers to connecting a part of an electronic device to the earth to maintain the device's potential at zero, the same as the earth's potential, and is also called grounding. The earth is a massive conductor with a potential of zero. For example, when earthing an electronic device, the device and the user in contact with it also become electrically part of the earth, so their potential can be maintained at zero. Meanwhile, static electricity is generated in the human body for various reasons. For example, static electricity or abnormal currents can accumulate within the body due to various invisible electromagnetic waves or factors in the surroundings. Static electricity accumulated within the body causes various problems, such as discomfort, reduced resistance to disease, inducing various inflammations or pain, and difficulty getting a good night's sleep. To address these issues, various studies on earthing are being conducted, and different types of earthing pads are being developed. However, when conventional earthing pads are made in a mesh form, users found it difficult to feel a sense of cushioning. Furthermore, there were problems that caused various inconveniences during use, such as a rough surface that easily became cold or hot depending on the weather.
