The invention discloses a capacitive electrocardiosignal acquisition composite film and a preparation method and device thereof. The capacitive electrocardiosignal acquisition composite film comprisesa flexible insulating substrate, an electrode arranged on the flexible insulating substrate, a semiconductor two-dimensional material arranged on the electrode, and an electrolyte polymer layer arranged on the semiconductor two-dimensional material. In the capacitive electrocardiosignal acquisition composite film, an electrode is modified by the semiconductor two-dimensional material to form a flexible metal electrode / semiconductor two-dimensional material, so that an electrical double-layer area of the contact surface of the flexible metal electrode / semiconductor two-dimensional material anda flexible electrolyte polymer layer is increased, the capacitance value of the whole capacitive electrocardiosignal acquisition composite film is increased, and the acquisition quality of capacitiveelectrocardiosignals is improved.
Description
technical field [0001] The invention relates to the technical field of electrocardiographic signals, in particular to a capacitive electrocardiographic signal acquisition composite film, a preparation method and a device. Background technique [0002] Cardiovascular and cerebrovascular disease is a common disease that seriously threatens the health of human beings, especially middle-aged and elderly people. It has the characteristics of high prevalence, high disability rate and high mortality rate. At the same time, pain points such as low awareness of chronic diseases such as cardiovascular diseases and irregular daily monitoring and management are one of the important reasons for the high prevalence of cardiovascular and cerebrovascular diseases. [0003] Wearable ECG monitoring equipment can be easily worn on the human body without affecting its normal life, and can realize long-term continuous monitoring of human cardiovascular diseases in daily life. ECG acquisition el...
