The principle of the heart rate chest strap is to measure the periodic changes of the cardiac current or electrical potential in the skin through the electrodes on both sides of the heart rate strap. And this current is so small that it is easily disturbed.
The first interference is other electrical noise signals in the skin. For example, tight muscles can also produce relatively large electrical noise. The way to prevent it is to make the heart rate belt close to the heart, which is less than 2 cm below the nipple in men, or the lower edge of the breast in women.
