As time goes on, our brains conti€∞λnuous innovation, so the ite¶Ω§βration, and constantly updated technolo‍₹÷gy to what we normallyβ♦↓ use the intelligent hand ring, <≠from our pointer type wat♠↑☆λches before update to t¶≤he development of electronic watche&≈s, directly to today's intelli₽≈÷gent bracelet, I think§ β$ what is the function of the intel∏±≥<ligent bracelet is bec'≈oming more and more perfect, I≥♠¥∞ found a lot of heart rate monitoring fδ←×unction, and blood pre♥∑ ™ssure monitoring function of the int≤¶↕ elligent bracelets, bracel>∏ets that I now say the heart ra≈↑αte of heart rate monitor this heart ra ↕te monitor!

For the moment, our common inte∏&lligent heart rate bracelet heart®✔→ rate monitor is usually divided intoΩ‍★ three kinds: one kind is ∞€φphotoelectric sensor, through δ$the light transmission measurements, inΩ​♣ principle, be a hand ring of cont✘εact with the skin sensor emits a beam∑β$ of light on the skin, measure ®±ment of the reflection/transmis♦γsion light. Because the pe€‌₩rson's blood to certain wavel•↔πengths of light absorption, every ti↑π me the heart pump blood×♥, the wavelength will be a large num♠¥←®ber of absorption, i→₩λ•n return for processed↑≈↕↑ analysis heartbeat to conve ₩α↕y to the connected phone App, the h↕✘α<eart rate data is not be displayed on ® the smart hand ring, c₽ γ an only be displayed througγλ✘→h the mobile phone App, the disad♦‌≤vantage of the photoelectric s↕δ±​ensor is a very power-hu↕₽§ngry, and is easily in×≠"fluenced by ambient light interference✔©±✘.

Intelligent monitoring brac↔☆πelet or watch currentl>★y on the market most the fu₽∏±nction of the heart rate is t≈¶↓>he transmission adopts the photoeleβ§ctric sensor measuring way∑δπ and make smart heart '↑bracelets.

Is another kind of ecg siδ€×gnals, the bracelet, ecg sign£ γal sensors can be mea✘↑sured by muscle contraction o£☆f the electrical signals to analyze÷•↔≥ the user's heart rate, pri∑÷ nciple and similar principle of ele×εctrocardiogram (ecg). '♣Ecg signal sensor condu•∑₩♦ctive circuit is more complex, the disa‌≤dvantage is circuit board need to do a↕γ lot of circuit board to λ♦accommodate, so use th γ"★is kind of ecg signal sensor intelligen×∞t hand from some larger, there iδ≠s also a weakness is very s  usceptible to electromagnetic in"•terference, but also to the ecg s‌✔↑ignal sensor close to t>✘¶he skin it is very necessary, when moni<₹toring the location of the relativ↔‍∏ely fixed, many intellige±±<nt bracelet manufacturer is hard to✔≥≥ put the ecg signal s≈☆☆&ensors to do the intelligence of sm•​πall and exquisite bracelet.

And there's a heart rat÷‍←e vibration sensor, using the±ε heart rate of vibration sensoαλr smart bracelet is rare on the <‍market, I guess it'$&;s because it is new and has n≠≈ ®ot been a large number of d♦≠<εevelopment using it (which I don&#ε♣39;t) are discussed. Because of ev♦✔ery heartbeat people ≥¥λ™will cause the vibration γ¶""of the body, and its work pri✘Ω♥nciple is to capture the user's¥↑≠ heart through high precision cause$☆d by the body's t≠"≥iny vibration, and back to the intellig×☆ent hand ring processing analysis §αagain to phone App, ag→ σ±ain by phone App displays a message to § the user. So we use intelligent heart ♥λ↑ bracelet can understand their he≠>Ω"art rate to the rhythm, and coarse ↔↑hair inspired us to e>↑¶∏xercise, running and so on.
