A biofeedback meditation relaxation device and method

Abstract

The invention discloses a biological feedback mental relaxation device and method and belongs to the field of biological feedback. The mental relaxation device comprises a skin resistance and skin temperature acquisition module, a skin resistance and skin temperature constant current source, a skin resistance and skin temperature sampling circuit, a skin resistance and skin temperature signal differential amplification circuit, a single chip microcomputer, a voice module and a power source. A skin resistance and skin temperature signal of a human body are acquired and converted into a voltage signal, the relative change voltage signal is subjected to differential amplification, skin resistance and skin temperature amplified voltage is subjected to averaging in a preset time period, mental relaxation features of the human body are judged according to changes of the statistical value, the voice module is controlled to reduce or increase the volume, a loudspeaker or headset is driven to give an audio prompt and voice to remind people of listening to the feedback, people enables the audio prompt to decrease gradually till disappear by training in quieting mental consciousness and relaxing body, and the purpose of mental relaxation is achieved. The device collects data conveniently and accurately, and is wide in application range.

Description

technical field [0001] The invention belongs to the field of biofeedback, and in particular relates to a device and a method for helping people relax in tranquility. Background technique [0002] Human beings are affected by external stress factors, and psychological and physical adverse reactions will occur. Excessive pressure is prone to depression, insomnia, anxiety, stage fright and other diseases. The pace of today's society is accelerating, and this problem is more prominent. It affects human work, study, life and Health output has been seriously affected, so how to alleviate people's stress has become an important topic to reduce the incidence of these diseases; [0003] At present, there are mainly research and development in the following aspects on this issue: [0004] 1. Research on brain wave biofeedback relaxation training, such as my country's patent No. CN201610567007.0, CN201320124545.4 invention patents, a disclosed method that collects brain waves and com...

AI Technical Summary

Problems solved by technology

[0011] 1. The above-mentioned bioelectrical signals collected have a certain effect in judging the relaxation state of the human body, and it is not easy to judge the state of tranquility of the human brain consciousness;

[0012] 2. The above-mentioned collected bioelectrical signals have low sensitivity to judging the relaxation characteristics of the human body, and are easily disturbed by the environment and individual differences, resulting in inaccurate judgment results;

[0013] 3. It is inconvenient to collect the above-mentioned bioelectrical signals, the device is complicated, and it is not easy to carry and use;

[0014] 4. Psychological intervention requires the intervention of others, without biofeedback, unable to self-regulate psychological pressure independently, at any time, and conveniently;

[0015] 5. Physical exercise is greatly influenced by external and own psychological factors, without biofeedback, adjustment of psychological pressure is prone to deviation
