I think what is the function of the intelligent bracelet is becoming more and more perfect, I found a lot of heart rate monitoring function, and blood pressure monitoring function of the intelligent bracelets.
As time goes on, our brains continuous innovation, so the iteration, and constantly updated technology to what we normally use the intelligent hand ring, from our pointer type watches before update to the development of, directly to today's intelligent bracelet, I think what is the function of the intelligent bracelet is becoming more and more perfect, I found a lot of heart rate monitoring function, and blood pressure monitoring function of the intelligent bracelets, bracelets that I now say the heart rate of heart rate monitor this heart rate monitor!
For the moment, our common intelligent heart rate bracelet heart rate monitor is usually divided into three kinds: one kind is photoelectric sensor, through the light transmission measurements, in principle, be a hand ring of contact with the skin sensor emits a beam of light on the skin, measurement of the reflection/transmission light. Because the person's blood to certain wavelengths of light absorption, every time the heart pump blood, the wavelength will be a large number of absorption, in return for processed analysis heartbeat to convey to the connected phone App, the heart rate data is not be displayed on the smart hand ring, can only be displayed through the mobile phone App, the disadvantage of the photoelectric sensor is a very power-hungry, and is easily influenced by ambient light interference.
