Electromagnetism suppressing material, electromagnetism suppressing device, and electronic appliance

Abstract

An electromagnetism suppressing material has an increased electromagnetism suppressing effect, can be flexibly formed in various shapes, and is inexpensive. An electromagnetism suppressing device uses the electromagnetism suppressing material, and an electronic appliance uses the electromagnetism suppressing material or the electromagnetism suppressing device. The electromagnetism suppressing material is a liquid material and/or gel material with electrical polarity.

Benefits of technology

[0025] According to the electromagnetism suppressing material of the present invention, a liquid material or gel material that has electrical polarity, such as an electrolyte or a molecular liquid material that has electrical polarity, is highly efficient at absorbing and suppressing electromagnetism, and can be cheaply formed as EMC compatible components that are flexible. By doing so, it is possible not only to greatly reduce the cost of measures against unnecessary radiation, but also to reduce the time taken by such measures through high efficiency. In addition, by mixing in magnetic powder, such material can be designed with even higher efficiency. Also, the electromagnetism suppressing material is flexible compared to existing magnetic materials, so that the mounting surface can be simplified and a wide range of uses can be real

Problems solved by technology

Increasing use of high-frequency electromagnetic waves in recent years has been accompanied by a new environmental problem of electromagnetic noise causing damage such as the malfunctioning of appliances and adverse effects on the brain and body.

Since the number and applicability of both potential sources of electromagnetism and interfered-with devices are increasing exponentially, the risk of interference occurring is increasing astronomically.

However, there are cases where the voltage and current waveform fluctuate due to a particular resonant frequency that depends on how the circuit elements are combined, with this resulting in a large distortion in the desired signal waveform.

In addition, the wavelengths of electromagnetic waves in a GHz band are close to the circuit length of an electronic circuit, so that there is the risk of malfunctioning due to the circuit itself acting as an antenna for the electromagnetic waves.

However, due to the complex signal transmission paths inside electronic appliances and t
