Product Details

   The heart is the source of blood circulation in the human body. Relying on the rhythmic beat of the heart, the blood continuously circulates in the body to maintain normal life activities.Wireless Ecg Electrodes Pcb Manufacturer1   



Before the heart beats, the myocardium first excites, and during the excitement, a weak current is generated, which is transmitted to the various parts through the human body. Because the tissues of different parts of the body are different; the distance between the parts and the heart is different, so in the human body Each part of the table exhibits different potential changes. These potential changes can be recorded by wires to the recording device, ie, the electrocardiograph, to form a dynamic curve. This is called electrocardiogram (ECG), also known as surface electrocardiogram. A normal human ECG can reflect changes in cardiac activation potential and consists of a series of repetitive waves, segments, and intervals.




 The electrocardiographic electrode sheet is made of a silicone rubber material or a non-woven material which is non-toxic and harmless to the human body. The ECG electrode sheet needs to detect multiple electrical performance indicators of the electrode sheet before leaving the factory. When detecting, the excitation source is usually added. However, the traditional excitation source circuit has poor anti-interference ability, is susceptible to interference from external signals, and has poor stability. The circuit structure is complex and consumes a lot of energy. It solves the problem that the traditional excitation source circuit has poor anti-interference ability, is susceptible to interference from external signals, has poor stability performance, and has complicated circuit structure and high energy consumption.
