Smart platform for air purification and domestic monitoring of humans activity
People, when shopping to buy a bed, actually go to buy a good sleep on it. Moreover, they go to buy freshness and recreation after a daily routine, that they will achieve when sleeping on it. In general, sleeping is very important for the whole society as one of the main factors defining people’s ability to work effectively and to live valuable life. In Europe and North America most people get their daily sleep in beds. However, the National Sleep Foundation has determined that 1/3 of American’s consider their sleep quality poor or fair, and the numbers are equally worrying for Europe. There are several reasons for lack of good sleep, including psychological factors, allergic reactions due to poor air quality, noisiness of the bedroom, uncomfortable bed, pains caused by different diseases, etc. One of the most important factors influencing sleep is the quality of air in the bedroom. Maintaining high quality of air is the first aspect of the proposed technology. Suitable air for sleeping must be fresh – low in CO2 concentration, free of dust particles and comfortable in the sense of humidity and temperature. Unfortunately, bedroom is typically a small room with insufficient ventilation. Therefore, CO2 concentration in the room rises over night, increasing breathing and heart rate of the sleeper, as well as motions during sleep, leading finally to waking up of the person. This problem can be solved, for example, by opening a window to let fresh air in. Unfortunately, in this case outdoor dust also migrates into the room. This project focuses on solving the problems related to the air quality in bed room. We purify air, using different technologies like direct air filtering as well as inhibition of microorganisms living on the bed mattresses. Technology is proposed also for monitoring of physical activity of humans on the bed. We measure breathing rhythms and hearth rhythms with help of non-contact methods. Options to monitor human health on the basis of collected data will be evaluated.
