As time goes on, our brains cont≥®♣inuous innovation, so the iteration, ¥'and constantly updateβ↓d technology to what ∞λwe normally use the iπ→≤​ntelligent hand ring, from ou ☆≥r pointer type watches before"¥≠σ update to the development of ele←∏ctronic watches, directly to to♠≠↔day's intelligent brace∏®let, I think what is the funct&✘σion of the intelligent bracelet i↕✘©s becoming more and more peγ↔δrfect, I found a lot ♦☆of heart rate monitoring fu←☆♠ nction, and blood pressure monitoring fΩ§unction of the intelligent bracelets, bracele >ts that I now say the h ‌>eart rate of heart rate mon®™∞•itor this heart rate monitor!

For the moment, our coσ ×mmon intelligent heart rate bracele•¥t heart rate monitor is usu₽"↔•ally divided into three kin∞>'ds: one kind is phot→©∞oelectric sensor, through the light transmγ>ission measurements, in >γ∏™principle, be a hand ring of contact with the ski↔α€n sensor emits a beam of light on the skinαΩ, measurement of the reflection/transmission ₹"↑ light. Because the person's bloo≈®¥d to certain wavelengths of light absorγ↑ption, every time the heart pump blood, t≤§ he wavelength will be a large number↕÷∞  of absorption, in return for processed analyφβ$♦sis heartbeat to convey to the connected p​ε≠βhone App, the heart rate data is not be ∞™≥displayed on the smart hand ring, can ÷♣only be displayed through the mobile ph♦✘one App, the disadvantage o≈‌™©f the photoelectric sensor is a very power-✔λδγhungry, and is easily influenced by ambient¥★‍÷ light interference.

Intelligent monitoring braφγ↓±celet or watch currently ' on the market most the funσφction of the heart rate is the transmission a© dopts the photoelectric sensor me↔αasuring way and make smart heart bracelets.

Is another kind of ecg signals, the braceletλ₹δ, ecg signal sensors can be measured by musc∞↔ ¶le contraction of the electrical signals to₽§ analyze the user's heart rate, principle♣>∞δ and similar principle of electrocardio♠★♠gram (ecg). Ecg signal sensor conductive c↔πircuit is more complex, the d≈φisadvantage is circuΩ>it board need to do a lot of cir€≥cuit board to accommodate, so use th↓"↓↑is kind of ecg signal sensor intelligent hand fr∏•↑om some larger, there is¶< also a weakness is very susceptible to electσ'↑romagnetic interference, but also to the ecg s✔♣‍€ignal sensor close to the skin ♦φit is very necessary, when monitorin  '←g the location of the relati‍®$‍vely fixed, many intellige∑¥nt bracelet manufacturer is hard to put t©&∞∏he ecg signal sensors to↓α®α do the intelligence of small and exquisite ★ bracelet.

And there's a heart rate vibration senσ♠★sor, using the heart r∏↓≥ate of vibration sensor smart bracelet is rare o←↓γn the market, I guess it's ↑≥♠♦because it is new and has no↑≥∑₹t been a large number of developme>♣✔nt using it (which I don't)÷≈γ₽ are discussed. Because of every heartbeat ↔₽✘"people will cause the vibr">₹ation of the body, and its wo↕α♥₽rk principle is to capture the us ₩¥er's heart through high precision cau♦←∑'sed by the body's tiny vibration, and back t• ↑≤o the intelligent hand ring processing analys‍∑₩★is again to phone App, again by ≈€phone App displays a me•‍ssage to the user. So we ÷&Ωuse intelligent heart bracelet can u×"nderstand their heart rate to the rhythm,‌≈™ and coarse hair inspired us to ✔§↔exercise, running and so on.
