TECHNOLOGY

01 Measuring sleep

measure

Analyze your sleep with unprecedented
precision

Using our proprietary algorithms based on sleep research and applying technology used in sleep research, we can reveal your sleep stage (depth of sleep), sleeping position, snoring/environmental sounds, and bed temperature (temperature inside the futon), which could not be seen with previous sleep measurement devices.

Sleep research x advanced AI algorithms

  • Sleep Stages

  • Snoring/Environmental Sounds

  • Sleeping posture

  • Bed temperature

Visualize "depth of sleep"

Using a unique sleep stage determination algorithm and sensors, it classifies your sleep into four deep sleep stages: [Awake], [REM sleep], [Light sleep], and [Deep sleep], and visualizes the duration of each stage. By knowing what time you wake up and how much deep sleep you are getting, it will help you create the optimal sleep rhythm for you.

Using a Sleep Coin (device)
will improve accuracy.


" Sleep Score " is evaluated based on sleep efficiency, etc.

It will score your sleep by analyzing your sleep time, sleep efficiency, and other sleep conditions. By measuring every day, you can also see changes in your sleep condition over the week and month. Aim for a high score!

Visualize and record snoring/environmental sounds that you
don't notice yourself

You probably have no idea how loud you are when you're sleeping, but using the app on this device will easily measure and visualize your snoring, and analyze the time and volume of your snoring.
In addition, AI will analyze the sound, distinguish between snoring and environmental sounds, and record them.
You can also listen to the snoring sounds yourself, sorting them by loudness.

You may not know, but
what's your best sleeping position?

Do you sleep in one position (on your back, on your stomach, or on your side)?
By comparing it with your sleep stages, you can see which position you sleep in when you are in deep sleep.
On the other hand, if you are troubled by snoring, knowing which position makes your snoring quieter can give you some hints on how to get a better night's sleep.

A sleep coin (device) is required for measurement .


Measure your body condition by the number of times you turn over in your sleep

Turning over in bed is an important factor related to the "sleeping state" and "physical condition." If you are using a mattress or pillow that does not fit you, you may find that you turn over very little.

A sleep coin (device) is required for measurement .


Measure the temperature in your bed , which affects your sleep

It's hot! It's cold! We've all had the experience of waking up in the middle of the night because of something like that, right? Controlling the temperature in your bed is very important for good sleep. Understanding the temperature when you sleep and controlling the temperature that changes with the seasons will help you create the optimal sleeping environment.

How to install

It is attached to the waist area
and does not come into direct contact with the skin, so there is no discomfort.

The clip type is easy for children to attach and does not come off easily. The clip is made of silicone and is soft to the touch, so it does not cause stress while sleeping.


It can measure the sleep of adults as well as children.

Sleep problems are not only a problem for adults, but also for children. Children's nocturnal lifestyles and reduced sleep time have a significant impact on their daily lives. Accurately understanding children's sleep patterns can be used to support their daily lives.

FAQ

About the app

Is the app itself free?

The app is free to use.
Paid features may be added in future updates, but rest assured that there are no features currently available to you that will become paid within the app, and no features that are currently free will become paid in the future. There will be no monthly fee if you continue to use the app.

Are there any communication charges?

Since the measurement is performed via Bluetooth connection, no communication will occur during the measurement. However, communication will occur each time you use the app for purposes other than measurement, such as downloading music, exchanging coupons, or reading articles.

How much of my phone's battery does the app use?

When using the Brain Sleep Coin app to measure your sleep, it will consume 40-50% of your smartphone's battery in one night, depending on how much it has depleted. We recommend that you keep the battery charged when using the app.

Can I use it with iPhone XX?

There are no restrictions on the model of your smartphone as long as it is compatible with the following versions
・iOS 15 and later
・Android 12 and later

Can measurements be taken multiple times a day?

Measurements are taken once a day. When you take a second measurement, the first data will be overwritten.

How will it be measured if someone other than me is snoring?

Although it is possible to measure individual information regarding sleep status,it is not possible to distinguish between snoring and that of others, so it is possible that it may detect snoring by others as well.
If you want to collect only your own sounds as much as possible, place the smartphone device as close to you as possible and take the measurement, which will allow for more accurate recording than when it is far away from you.

Is there a snooze function?

The snooze function for the wake-up alarm can be set if you set an alarm within the app. Also, if you want to wake up using the alarm function on your smartphone, you can turn off the alarm within the app and use it. (In that case, you will need to open the app and stop the measurement when you wake up.)

Is there any collaboration with healthcare?

Currently, data is not displayed via Health app integration.
In future updates, data linked with the Health app may be used within Brain Sleep Coin, and further updates may be made.

How to use coins

Can I measure using only the Brain Sleep coin?

This product uses an app to measure, so it is possible to measure using both the app and the device. Measurements cannot be made using the device alone.

Can two people measure one Brain Sleep Coin?

Two people can use one Sleep Coin, but each person must download the app. You can
unlink the app, so if you unlink the app and then link it to another app, two people can use one coin. Each person can use it at a time, and two people cannot use it at the same time.

If I purchase two Sleep Coins and two people use them, can I view both people's data in one app?

Each sleep coin corresponds to one app.
Therefore, you cannot view data for two sleep coins (two people) in one app. Also, you can only record one sleep data per day.

Can it be used as a one piece dress?

This product is designed to be worn around the waist of pants and cannot be worn with a dress.

How can I replace the battery in the device?

No tools such as a screwdriver are required; replacement can be done manually.
For details, please refer to the instruction manual after purchase .
Battery: CR2032 coin battery (3V)

How long does the battery last?

It depends on the usage environment and frequency of use, but the estimated life span is about 4 to 6 months.
*The initial battery included is a test battery, so the remaining charge may vary from one battery to another.

Can I use my smartphone in another room?

You will not be able to measure snoring, but you can still measure within Bluetooth range. *You will need to press the start button to start the measurement.

    意外と簡単

    使い勝手もよく、計測も簡単でした。毎日の睡眠の状況を知れるのは良いと思います。

    睡
    睡眠時無呼吸太郎
    スマートウォッチと比べながら使ってます

    お腹につけるタイプのため、ときどき付けているのを忘れてトイレで慌てます。睡眠測定は、寝返りと温度が測れるのが特徴です。あとはスマートウォッチと併用することで、睡眠の傾向がよく分かります。イビキが自動録音されるのは、とても面白いです。アドバイスのメッセージは、いつも変わらないのが、改善点でしょうか。

    お手軽な上に高性能な睡眠測定器と専用アプリ

    ◯購入のきっかけ
    家族が同じものを使用しており、「今日は深い睡眠が多かったからスッキリ目覚められた〜」や、「つい(仕事が)休みだからいつもより長く寝たけれど、結局いつも起きる時間以降はずっと浅い睡眠だったからか、あまりスッキリしなかった。。。」など、かなり興味深い話を聞いていたため、ちょうどセールでもあったため購入しました。
    ◯本体の使用感について
    よくある腕時計型の睡眠測定器具とは異なり、こちらはズボンなどに挟んでへそのあたりに固定するものです。大きさは名称のとおりコインサイズでとても軽く、装着中は全く重さを感じませんでした。
    クリップ部はかなりしっかり挟んでくれるので、途中トイレなどに行っても落とすことはまずないと思います。
    実は以前腕時計型のものを使用していたのですが、どうしても寝ている時に手首に圧迫感や不自然な重さがあるのが不快な上、普段は外で腕時計として使っているものなので衛生的にどうしても寝る前に毎回洗いたくなり、結局面倒になり数日で使わなくなりました。
    こちらはまず睡眠時のみ使用する端末なので日中は箱などに入れて衛生的に保管することができ、装着も体の中心部分のへその辺りなので、左右に寝返りをうっても仰向けで寝ていても手足をどこに向けたとしても、全く普段と変わらず違和感がなく、リラックスして寝ることができます。
    電池交換も本体を手のひらなどでスライドさせるだけで交換可能なので、寝る前にうっかり電池がなくなっていたとしても、わざわざネジを回すドライバーを探す必要はなく、ぱぱっと交換可能です。
    充電式ではないためこのようにすぐに再使用することができ、電池さえストックしておけば毎日欠かさず使用できます。
    購入して30日間ほど毎日1回6〜8時間ずつ使用し続けていますが、現在電池残量は満タンの3メモリ分あるようですので、この様子なら電池１個あたり2〜3ヶ月くらいは持つのではないかと思います。
    ◯アプリの使用感について
    専用のアプリ(iOS、Android両対応)があるのですが、この小さな軽いデバイスからは想像できないほど多様な情報を記録解析してくれます。
    まず眠りの深さについて、「覚醒」「レム睡眠」「浅い睡眠」「深い睡眠」の4つに分けられており、寝ている間グラフでこれら4つが何時ごろに起きたかを記録してくれます。また同時に寝てすぐ90分間に深い睡眠が十分取れていたかを金銀銅のメダルで表現されており、またそれぞれ4つの状態が合計で何時間くらい取っていたかも表示されます。
    また中途覚醒の回数と合計時間、二度寝の回数と起きるまでにかかった時間、も表示され、これらを毎日見ることで、自身の睡眠にある問題点や改善方法などを確認することができます．
    画期的なのはこれらと合わせて寝床内温度を重ねて表示することができる点です。
    私の場合は暑すぎるのは眠れないと思いクーラーを強めにつけて寝ていたのですが、どうやら寝ている間の温度が低すぎるようで、設定温度を上げて寝てみてところ、スッキリ眠ることができました。
    また、これらの情報をじっくり見る余裕がないときなどのために、「あなたへのアドバイス」として毎日結果に基づいてコメントが届き、またそのコメント内容に応じたおすすめの記事も表示できるため、どのような方でも睡眠が改善できるような工夫がされていると思います。
    ◯総括として
    デバイス本体の仕様1つ1つに、普段寝ている時に使うものであることを意識したこだわりの作りとなっていると思います。
    またアプリもアップデートで機能追加を行い、よりわかりやすく使い勝手の良いものになるよう、現在も日々開発し続けられていると思います。
    本体を1つ買うだけで毎月の契約などが一切ない無料のアプリを使えるのは、大変魅力的ではないかと思います。
    その無料のアプリも、機能が追加されても追加料金を取ることはなく、アップデートも無料で現在も開発し続けられているのも、やはりこちらのメーカーが睡眠の質に特化した寝具類を専門に扱う会社だから、それだけ他社以上に顧客の睡眠の質を上げたいという思いが強いからだと思います。
    もしまだ購入を迷っている方がいるのであれば、是非購入してみてはいかがでしょうか。
    とても信頼できるメーカーであると思います。

    最初はどうなのかな。と半信半疑でいたが、実際使ってみればわかりますが、自分の睡眠を評価してくれることがこれほど改善意識を高めてくれるとは思わなかった。もっとよく眠りたいと考えるようになったし、スコア状況ど自分の睡眠について見直すきっかけになります。
