What is Baby-Carrying Mode?

Baby-Carrying Mode uses the Polar VeritySense wrist-worn optical sensor (hereinafter referred to as the sensor) manufactured by Polar.

*If you do not have the sensor, please use the trial version of Baby-Carrying Mode.

In this mode, attach the sensor to your baby's calf or thigh (Note 1) and follow the voice guidance to carry your baby while walking.

During measurement, you can view your baby's heart rate status as a graph.

Note 1) While the location where the pulse signal (PPG, red wave) is most visible varies by individual, we recommend positioning the sensor's green light slightly above or below the back of the knee. Please refer to the manual's diagram.

※ Initial setup is required upon first use after installation. Please check the Initial Setup page.

Connect the Polar VeritySense sensor to the app

Attach the sensor to the baby

Wait 30 seconds or 5 minutes (random)

Pre-notification and baby status memo

Walking while holding baby for 5 minutes with BGM

(If crying persists, walking while holding baby may be extended once for 5 minutes)

Wait seated for 8 minutes

Lay the baby down on the futon

Input baby's condition, notes, etc.

Send the record

From attaching the sensor until laying the baby down on the futon, you can check the heart rate graph (HR, yellow line) and photoplethysmography graph (PPG, red wave) at any time.

The entire process takes approximately 15 to 30 minutes.

The sensor cannot start if its battery is below 30%.

Please charge it beforehand using the dedicated USB charger.

If the sensor glows green while charging, it is sufficiently charged.

If it glows orange, it is still charging but you can start carrying your baby.

If it flashes red, the battery level is insufficient. Wait for charging to complete, or if you are in a hurry, use the “Trial Version Sleep Mode” without the sensor.

*The indicator light behavior may change due to Polar Verity Sense sensor updates.

Detailed battery level will be displayed in 10% increments after the next connection step.

A new Polar sensor can operate continuously for over 10 hours from a 100% charge.

*Rated for 30 hours

*If the sensor detaches from the belt, there is a risk of aspiration. Always remove the sensor after putting the baby to sleep.

The included PolarVeritySense sensor belt is designed for adult arms and may be too long to fit securely on infants with smaller wrists or slender legs. In such cases, adjust the belt to a shorter length beforehand. You can either cut and resew it, or use a slip stitch to shorten it by approximately 5 cm.

When you start the mode, it will first search for nearby sensors. At this time, your smartphone settings will prompt you to enable Wi-Fi, Bluetooth, and other necessary permissions. Please follow the app's instructions to complete these settings.

Once the search begins, turn on the sensor's power and connect to the displayed device. Sensors charging will also appear, but they will not function properly while charging. (Charge levels and graphs will not display correctly either)

※If you have two or more sensors, multiple devices will be displayed. In this case, please check the Device ID on the sensor's side.

After connecting the sensor and starting measurement, the screen will display the PPG (photoplethysmogram, red line) graph.

Place the sensor directly on the baby's skin, slightly above or below the back of the knee. If the belt is too loose, the sensor will move. If it is too tight, the sensor may obstruct blood flow beneath the skin, making pulse measurement difficult. Adjust the belt so it fits snugly and securely against the skin without moving. It is acceptable to dress the baby in pants over the sensor.

The optimal sensor position varies between individuals. Gradually adjust the sensor's position until the red waveform (pulse wave) appears regularly at a depth of at least one mark, as shown in the figure. It is best to find a good position initially when the baby is calm and quiet.

When the sensor position and belt tightness are properly adjusted, the pulse wave will stabilize and appear at a depth of at least one mark (Figure 1). Once this occurs, proceed to the next screen.

※ If the baby is crying or moving actively, the red line may become significantly distorted, making it difficult to see regular waves (Figure 2). In such cases, try holding the baby to calm them down before adjusting the sensor.

※ Avoid extremely bright locations, such as direct sunlight or under large fluorescent lights, as these can easily cause wave distortion.

To stabilize sensor readings and predict the optimal time to put your baby to sleep, there will be a random waiting period of either 30 seconds or 5 minutes. If your baby is crying, it's okay to soothe them by sitting down and holding them, patting them, or talking to them. However, please refrain from walking while holding them until the waiting period ends.

During this time, please complete the questions regarding your baby's condition and the use of baby carriers or slings. Also, please use the waiting period to ensure the walking area is clear and free of tripping hazards.

If using a baby carrier or sling for walking, please place your baby in the carrier and get ready when the signal is given.

After three counts (beats), begin the 5-minute baby-carrying walk.

Walk with your baby to the music at a steady tempo, trying not to stop as much as possible.

(You can change the background music in the app settings.)

The key is to keep walking steadily until the end signal, even if your baby falls asleep while walking.

Before placing your baby in the bedding, wait for 8 minutes while sitting in a chair or on the sofa. Some babies may fall asleep during this time.

The narration volume will be slightly lower from here on, but if the sound still wakes your baby, it's best to keep the volume moderately low.

If your baby wakes up during this time or hasn't fallen asleep yet, press the “Extend” button to resume pacing with your baby.

When you hear the cue “Let's lay the baby down on the futon,” try putting the baby to sleep.

If the sensor accidentally comes off the belt, there is a risk of aspiration. Therefore, after laying the baby down, always remove the sensor and place it somewhere the baby cannot reach.

Record your baby's condition and notes at each time point. The notes field can be left blank.

※Please do not include any personal information.

It also includes several questions for research purposes.

Thank you for your cooperation.

You can view the condition and notes for each time point later in Record Data Mode.

After that, data will be sent (uploaded) to the server.

Depending on your connection speed, uploading 15 to 30 minutes of measurement data typically takes about 1 to 3 minutes over a standard Wi-Fi connection. After transmission completes, close the SciBaby app.

If the connection is lost during transmission, the upload may fail. In this case, the app will attempt to resend the data the next time you open the Baby-Carrying Mode. For smoother operation, open the Baby-Carrying Mode in advance and follow the prompts to confirm and perform the resend upload.
