Puas tau txij li thawj Fitbit tau tshwm sim, ntau lub zog trackers tau coj qhov chaw tseem ceeb hauv ntiaj teb thev naus laus zis. Txawm hais tias Fitbit nyob deb ntawm thawj qhov kev tawm dag zog, nws tau tso lub hauv paus rau ntau lab nyiaj daus las uas lub cev hnav tau tsim hnub no.
Niaj hnub no lub zog trackers yuav tsum muaj peev xwm taug qab lub plawv dhia yam tsawg kawg nkaus. Raws li qhov ntsuas kev noj qab haus huv mus, nws yog ib qho tseem ceeb tshaj plaws - thiab ob peb lwm yam kev ntsuas muab cov txiaj ntsig tam sim ntawd. Lub plawv dhia ncaj qha qhia koj qhov kev tawm dag zog thiab tuaj yeem pab koj kho koj qhov kev cob qhia kom ua tau raws li koj lub hom phiaj. Kev so lub plawv dhia kuj tuaj yeem yog qhov tseem ceeb ntawm koj txoj kev noj qab haus huv tag nrho (feem ntau, qis dua yog qhov zoo dua).

Photoplethysmography
Yog li cas koj lub smartwatch ntsuas koj lub plawv dhia txhua hnub hauv lub cev me me li cas, txawm tias hnub tsis tau them nqi? Feem ntau smartwatches siv cov txheej txheem hu ua photoplethysmography. Yeej, nws siv lub teeb los sau cov kev hloov pauv hauv qhov ntim ntawm koj cov hlab ntsha. Feem ntau cov smartwatches ua tiav qhov no nrog lub teeb ntsuab LED thiab photodetector.

Lub teeb ntsuab illuminates daim tawv nqaij, cov ntaub so ntswg thiab cov hlab ntsha hauv qab, thaum lub photodetector ntsuas feeb hloov ntawm lub teeb pom kev. Raws li cov hlab ntsha nthuav dav thiab sau nrog cov ntshav, lawv nqus lub teeb ntsuab ntau dua; raws li lawv shrinkage, lawv xav tau ntau lub teeb ntsuab. Cov kev hloov pauv no tsim cov nthwv dej hu ua photoplethysmogram (PPG), uas nws lub ncov thiab cov troughs qhia lub plawv dhia. Lub teeb ntsuab yog siv vim nws tsis nkag mus rau ntawm daim tawv nqaij kom tob li lub teeb liab thiab infrared.
Electrocardiography
Cov txheej txheem kub rau kev ntsuas tsis cuam tshuam ntawm lub plawv yog electrocardiogram - EKG. Txawm hais tias EKG hnav tau nyob ib ncig ntawm kaum xyoo, nws tsuas yog muaj nyob rau ntawm smartwatches txij li xyoo 2018. Lub EKG ntsuas cov hluav taws xob ua haujlwm ntawm lub plawv los ntawm kev sau cov ntaub ntawv los ntawm electrodes txuas rau ntawm daim tawv nqaij. Cov electrodes no khaws cov cim hluav taws xob me me ntawm lub plawv contraction thiab so uas mus thoob plaws lub cev. Thaum lub tsev kho mob EKG feem ntau siv 10 electrodes, cov khoom siv zoo li Google Pixel Watch lawv tsuas siv ob.

Yuav ua li cas qoj trackers ntsuas ntshav oxygen saturation
Cov ntshav oxygen saturation (SpO₂) tuaj rau hauv lub qhov muag rau pej xeem thaum ntxov li 2020 thaum COVID pib muaj xov xwm. Txij thaum ntawd los, yuav luag txhua lub smartwatch thiab qoj tracker muaj cov cuab yeej los sau nws. Txawm hais tias kev paub txog SpO₂ tuaj yeem muab tau informace hais txog koj txoj kev noj qab haus huv tsis yog qhov tseem ceeb tam sim ntawd rau koj lub cev kom paub txog koj lub plawv dhia. Raws li nrog lub plawv dhia, lub zog trackers siv PPG thev naus laus zis los suav SpO₂. Txhawm rau txheeb xyuas qhov piv txwv no, cov watches ntse thiab lub cev qoj ib ce tsim PPG nthwv dej los ntawm ob lub LEDs, ib qho liab thiab ib qho infrared. Los ntawm kev sib piv qhov siv ntawm ob lub teeb liab, SpO₂ tuaj yeem kwv yees.

Yuav ua li cas qoj trackers thiab wearables ntsuas lub cev rog
Fitness trackers uas kuj ntsuas lub cev rog thawj zaug pib tshwm sim nyob ib ncig ntawm 2020. Smart watches xws li Samsung Galaxy Watch5, kwv yees lub cev rog feem pua (thiab tag nrho lub cev muaj pes tsawg leeg) siv cov txheej txheem hu ua bioelectrical impedance tsom xam (BIA). Lub dab teg uas siv BIA xa hluav taws xob los ntawm caj npab thiab ntsuas qhov sib txawv ntawm cov teeb liab hluav taws xob ntawm ob qhov kawg.

Vim tias cov dej yog lub cev tseem ceeb ntawm hluav taws xob, BIA qhov tseem ceeb muab kev kwv yees (raws li koj qhov siab, qhov hnyav, thiab poj niam txiv neej) ntawm koj lub cev dej tag nrho. Feem ntau ntawm cov dej nyob rau hauv peb lub cev muaj nyob rau hauv cov ntshav, cov nqaij ntshiv thiab lub cev; nws muaj tsawg heev nyob rau hauv nws cov rog reserves. Feem ntau, kwv yees li 73% ntawm cov dej muaj nyob hauv cov rog tsis muaj rog ntawm peb lub cev. Los ntawm kev rho tawm cov rog no los ntawm tag nrho lub cev qhov hnyav, peb tuaj yeem kwv yees qhov feem pua ntawm lub cev rog.
Yuav ua li cas Fitness Trackers ntsuas cov tawv nqaij kub
Qhov kub ntawm daim tawv nqaij tau dhau los ua ib qho tseem ceeb ntawm cov kev tawm dag zog, tshwj xeeb tshaj yog cov poj niam taug qab lawv lub voj voog ovulation. Fitness trackers ntsuas qhov kub ntawm daim tawv nqaij siv cov ntsuas kub infrared uas siv cov thermocouple thiab thermistor.

Yuav ua li cas qoj trackers thiab smartwatches suav cov kauj ruam
Kev suav cov kauj ruam yog lub hauv paus ntawm qhov kev lag luam niaj hnub qoj tracker tsim. Tsis zoo li qee qhov ntawm lwm cov thev naus laus zis uas peb tau tham txog tam sim no, kev suav cov kauj ruam yog qhov tsis tseem ceeb. Yuav luag txhua txhua lub zog tracker, smartwatch, thiab smartphone muaj peb-axis accelerometer, ib qho khoom siv hluav taws xob uas tuaj yeem ntsuas kev hloov pauv hauv kev nrawm thaum koj txav mus los thiab nqis, pem hauv ntej thiab rov qab, thiab sab laug thiab sab xis. Los ntawm kev tshuaj xyuas lub ncov thiab troughs ntawm accelerometer cov ntaub ntawv thiab muab piv rau cov paub tib neeg taug kev qauv, tus naj npawb ntawm cov kauj ruam ib tug neeg tau ua yuav kwv yees kwv yees.
Ntxim qab kawg..kuv nyiam nyeem heev 👍🏽
