Double smart bed/mattress

Now, most smart beds have sleep monitoring function, so can smart beds with sensor monitoring function achieve two-person monitoring? That is to say, can a bed automatically and stably recognize the sleep sign data of two people at the same time?

In the existing technology, the intelligent double bed with sleep monitoring needs to be equipped with two sleep monitoring belts on the mattress to detect the sleep rate, respiration, body movement and other dimensions of the sleeper to judge the user’s sleep. In order to detect the tiny heart rate and respiration of sleepers, two monitoring belts with very high sensitivity are generally required to be laid under the double bed. However, when the double bed is used alone, when no one is sleeping on the other side, it will be affected by the heart rate, respiration, body movement or external vibration of someone sleeping, which will clearly lead to one person sleeping, but sleep reports will be issued on both sides, Even the side where no one sleeps reports a lot more problems than the side where some people sleep; If you use or set up a less sensitive monitoring band, when the user enters deep sleep, the breath and heart rate will become weak, and the problem that the user information cannot be monitored will occur at this time, which will affect the user’s sleep quality assessment.

The simultaneous monitoring of two people in bed is one of the difficulties of sleep monitoring. It not only requires the sensor hardware to have strong anti-interference ability, but also challenges the software algorithm. If one person sleeps on the mattress with two built-in sensors, and the other person sleeps in the middle or on the other side, or rolls from the middle to the other side, although both sensors can detect the signal, they have corresponding characteristics in signal strength, time and frequency, which can be used to help judge whether the signal is generated by one or two people.

The piezoelectric thin film sensor of Plus1Health can respond sensitively to weak dynamic signals, such as breath and heart rate signals. The sleep monitoring belt is laid on the bed. When a person is lying on the bed, the breathing fluctuation and heart beat are captured by the piezoelectric film sensor, and the respiratory and heart rate values are calculated. The piezoelectric thin film sensor of Plus1Health has excellent anti-interference ability. Only when people are lying in bed, the thin film piezoelectric sensor will output pressure signal, thus reducing misjudgment.

The sleep monitoring solution for double smart bed/mattress of Plus1Health can realize the installation of two intelligent sensors for the intelligent double bed, which is used to monitor the sleep sign data of two people at the same time, and can automatically and stably identify the sleep sign data.
