The system is good in integration density and stretchability and high in applicability.

Description

technical field [0001] The invention belongs to the related technical field of medical health detection equipment, and more specifically relates to a skin-attached ECG acceleration detection system and a preparation method thereof. Background technique [0002] Nowadays, with the rapid development of society and economy, people's life rhythm is accelerated, and the pressure of life is also increased. This undoubtedly increases the incidence of heart disease. Abnormal ECG waveforms will appear in the early stage of heart disease. If there is an abnormality in the exercise situation, taking corresponding measures in time can effectively reduce the serious impact caused by the deterioration of the condition. But at present, traditional medical methods mostly use long-lead ECG monitors, which not only limit the freedom of movement of patients, but also occupy expensive medical equipment, causing serious economic burdens to patients' families. Therefore it is very important to s...

Problems solved by technology

[0003] With the continuous development of electronic information technology, emerging electronic fields related to flexible electronics, such as plastic electronics, organic electronics, and printed electronics, have emerged in recent years. Flexible electronics have unique ductility, good wearability and can be carried out. With the advantages of large-scale manufacturing and low cost, it is widely used in medical, energy, military, education and other fields. The flexible electronic products that have been developed include printed RFID, flexible display, organic light-emitting diode OLED, etc., because they are different from traditional hard Circuits can realize functions such as bending and stretching, and are widely used in real life. Traditional micro-nano electronics use photolithography, electron beam and ion beam etching to achieve micro-nano-scale processing. The process is complex and Due to high manufacturing costs and high environmental requirements, it is difficult to meet the large-area, mass-scale, and high-adaptability production requirements of flexible electronics. Stable and efficient process methods have great application prospects and significance

At present, most multi-functional flexible integrated circuits have the problems of low integration density, large stretching limitations, and the above two are usually difficult to meet at the same time, resulting in large circuits and insufficient flexibility, which greatly reduces the wearing comfort and portability. sex
