Skin resistance measuring method based on multiple channels

Abstract

The invention provides a skin resistance measuring method based on multiple channels. The method comprises the following steps: constructing a skin resistance measuring device based on multiple channels, wherein the skin resistance measuring device comprises a plurality of electrode groups; the electrode groups comprise multiple electrodes and a channel selector; multiple channels are formed amongthe multiple electrodes; and each electrode group is connected with the channel selector and is used for selecting multiple electrode groups; selecting one electrode group, and acquiring signals of skin resistance change at different parts of a human body; constructing a calculation circuit in each channel, and calculating signals of skin resistance change; and performing data superposition on the signals of skin resistance change calculated in different channels. The problem that the measurement precision is not accurate as the sweat gland at a human body part of an electrode is not well developed when skin resistance is measured through a single channel can be solved by multi-channel compensation constructed on the single channel, after superposition of signal data acquired by multiplechannels, the signal data are used as skin resistance values of testing points, and data sampling accuracy can be improved through multi-channel measurement to the maximum extent.

Description

technical field [0001] The invention relates to the technical field of skin resistance measurement, in particular to a multi-channel-based skin resistance measurement method. Background technique [0002] With the rapid development of social economy, social pressure has caused different degrees of psychological distress to people. Studying the relationship between human skin resistance signals and emotions can not only help people better improve their mental state, but also timely intervene and Correct your own mental problems. At the same time, this research can also be applied to the study of the driver's driving status, the merchant's understanding of the shopper's points of interest, etc., which is of great value in promoting the research of human factors engineering. [0003] At present, all methods of measuring skin resistance in the prior art are based on two points of fingers or palms, that is, a pair of electrodes are placed on the skin surface, a voltage is applied...

AI Technical Summary

Problems solved by technology

This kind of measurement method has very strict requirements on the parts, and the measurement accuracy is not accurate enough, especially in some scientific research fields, when the finger or palm of the subject is occupied by other equipment, it is impossible to measure the skin resistance.

In addition, some devices in the existing technology use skin resistance collection at two points on the wrist, and its measurement accuracy is far inferior to that on the finger. This is because the sweat glands of the human wrist are compared with those of the fingers. Underdeveloped, the skin resistance of the fingers is more pronounced when mood swings occur
