Embodiment 1

[0025] The present embodiment is a human tissue simulating fluid for SAR testing, which is a tissue simulating fluid of a low-frequency human body part and includes the following components:

[0026] 1) Sucrose, the purity of sucrose is required to be greater than 98%, which is mainly used to reduce the relative dielectric constant, and its weight ratio is 51.17%;

[0027] 2) Salt, the purity of the salt is required to be greater than 99%, which is used to increase the electrical conductivity, and its weight ratio is 2.34%;

[0028] 3) Deionized water, the resistance of deionized water is required to be not less than 16 ohms, which is mainly used to increase the dielectric constant and reduce the conductivity when preparing the solution, and its weight ratio is 46.21%;

[0029] 4) Cellulose, cellulose is mainly used to increase the viscosity and maintain the dissolved state of sucrose, to prevent the crystallization of sugar in the solution, resulting in changes in the dielect...

Embodiment 2

[0043] The present embodiment is a human tissue simulation liquid for SAR testing, which is a tissue simulation liquid of a low-frequency human head and includes the following components:

[0044] 1) sucrose, the sucrose purity requirement is greater than 98%, and its weight ratio is 57.9%;

[0045] 2) Salt, the purity of the salt is required to be greater than 99%, and its weight ratio is 1.38%;

[0046] 3) Deionized water, the resistance of deionized water is required to be not less than 16 ohms, and its weight ratio is 40.29%;

Abstract

The invention discloses human tissue simulation liquid for SAR testing. The human tissue simulation liquid for SAR testing comprises the following components: 1) deionized water of which the resistance is not less than 16 ohm; and 2) one or more of salt with purity greater than 99%, saccharose with purity greater than 98%, celluloses, a preservative and diethylene glycol monobutyl ether. The problems that at the present stage, human simulation tissue liquid is frequently maintained in daily life, and is high in cost, and every frequency band is narrow.

Description

【Technical field】 [0001] The invention belongs to the technical field of human simulation, in particular to a human tissue simulation liquid for SAR testing. 【Background technique】 [0002] With the development of information technology and manufacturing industry, when the public enjoys various conveniences brought by wireless communication equipment, they are increasingly concerned about the impact of electromagnetic radiation from wireless communication terminals on human health; whether the radiation generated by mobile phones is harmful to human health Harmful, there are still two diametrically opposed views, and both views lack medical clinical evidence. However, both industry and government believe that it is necessary to propose a safety limit value of SAR to guide production. At the same time, standard-setting organizations and government agencies are continuing to grasp the latest scientific discoveries to determine whether the safety limit requirements need to be m...
