Description

Technical Field

[0001] This invention belongs to the field of health monitoring technology, and in particular relates to a conductive paste, a health monitoring coating, and a smart fabric. Background Technology

[0002] A study published in the authoritative American medical journal *The Journal of Strength and Conditioning Research* investigated whether electrical muscle stimulation (EMS) could help elite athletes achieve better performance. The study concluded that while highly trained elite athletes already possessed excellent physical attributes, EMS could significantly enhance their strength levels, reaching levels achievable by athletes who had not undergone EMS training. They further pointed out that EMS provides a new alternative to traditional training methods to enhance athletes' strength parameters and athletic capabilities. Indeed, many athletes have used EMS technology to improve their performance, with Usain Bolt, the world record holder in the men's 100m, 200m, and 4x100m relay, being a prime example.

It has the advantages of being highly applicable and comfortable, and can solve the shortcomings of traditional low-frequency products, such as complex manufacturing process (conductive fibers) and discomfort (conductive rubber).

[0049] The present invention also provides a wearable health monitoring device, comprising the aforementioned smart fabric.

[0050] According to the present invention, the smart fabric also includes a control system; the control system is electrically connected to the health monitoring coating; the control system includes a signal acquisition module for collecting the current collected by the health monitoring coating; for example, during myocardial activity, current is generated, which reacts with the conductive tissues and body fluids around the heart to the surface of the human body, and can then be collected by the health monitoring coating and transmitted to the control system. By using microelectrode technology to record the voltage changes of the heart tissue as a graph, an electrocardiogram can be obtained.

[0051] More specifically, the control system also includes a health detection module, which is used to perform electrocardiogram analysis, heart disease classification, and body fat analysis based on artificial intelligence algorithms such as deep learning. The algorithm processes electrical signals and converts them into corresponding health data, with a dynamic detection accuracy rate of over 99%.

[0052] More specifically, the control system preferably also includes a transmission module, specifically a Bluetooth module; the transmission module can transmit health data to terminal devices to achieve real-time health monitoring. The terminal devices include, but are not limited to, mobile phones and / or cloud servers.

They can identify heart rate abnormalities such as atrial fibrillation, premature beats, tachycardia, or bradycardia. When abnormal physiological information is detected, an alarm will be triggered on the control system and / or the terminal devices.

The control system further includes a power module for controlling the electrical pulse coating to output a current of 0-15mA. More specifically, the control system controls the current output of the health monitoring coating in a pulse mode, using a positive and negative symmetrical bidirectional rectangular pulse wave. The principle of electrical pulse is to simulate the transmission of electrical signals in the brain. By outputting microcurrent stimulation to the electrical pulse coating through the control system, the signal is directly transmitted to the muscles, causing the muscles to passively contract. At the same time, simple fitness movements are performed, allowing the passively contracting and actively moving muscles to produce a strong contraction response, accelerating fat consumption and muscle formation.

[0055] The smart fabric is connected to the control system via a fastening mechanism. When the smart fabric comes into contact with the skin, it can collect body electrical signals in real time and transmit these signals to the control system. The control system uses artificial intelligence algorithms based on deep learning to perform electrocardiogram analysis, heart disease classification, and body fat analysis. The algorithm processes the electrical signals and converts them into corresponding health data, achieving a dynamic detection accuracy rate of over 99%. Simultaneously, the health data is transmitted in real time to terminal devices such as mobile phones or cloud servers. When the mobile phone receives the health signal, it displays physiological information such as electrocardiogram, heart rate, body temperature, body fat, mood, and sleep quality. It can identify heart rate abnormalities such as atrial fibrillation, premature beats, tachycardia, or bradycardia. When abnormal physiological information is detected, alarms are triggered on the host device, mobile phone, and cloud server. The cloud server analyzes and stores the user's physiological information and generates corresponding health reports, providing real-time assessments, dietary recommendations, disease risk assessments and suggestions, intelligent early warnings for heart diseases, and feasible clinical diagnostic plans.
