A Feasibility Study on Smart Mattresses to Improve Sleep Quality

Abstract

Good sleep quality is essential, especially for clinical users. Sleep disorders not only impair the success rate of treatment but also delay recovery. They can seriously interfere with treatment outcomes and even endanger a user’s life. In this study, we created a smart mattress containing 10 × 18 air packs and control units. Each air pack contains a set of pressure and height sensors and two air valves. Each row control unit can detect and adjust the pressure and height of each air bag in the row. When the bed body is turned on, it automatically initializes, adjusts the state of each air bag to the same height and pressure, and enters a slow scanning state. When perceived objects or people are lying on the bed, the bed automatically perceives the human body structure and body pressure matrix, increases the scanning speed for more timely and accurate measurements of the digital matrix and forming pressure by matrix-normalized processing, and then uses local pressure variance detection to automatically adjust to the sleeping position of the human body and thus achieve a uniform force distribution and a comfortable state. Finally, pressure matrix binarization was used to match sleeping position templates to identify the best template for automatic recognition of the sleeping position. The experimental results show that the sleeping position recognition method has high accuracy, recall, and precision. Our mattress is designed with interfaces for external devices. In future research, the smart mattress can connect to an auxiliary part of a smart ecosystem consisting of a smart pill box, a smart lighting system, and a microclimate system, which is expected to yield a more comprehensive intelligent ward to explore the possibility of improving sleep quality.

Association of Sleep Duration with Cognitive Performance in the Elderly: A Cross-Sectional Study from National Health and Nutrition Examination Survey (NHANES)

“…An extended sleep period may disrupt the normal circadian rhythm, resulting in abnormal levels of neurotransmitters in the brain during a speci c period, thus affecting cognitive functions such as memory and language [27][28][29]. Second, the effect of sleep on brain neurotransmitters excessive sleep may lead to disorders in the level of neurotransmitters in the brain, especially those closely related to cognitive function, such as acetylcholine [30]. This may hinder the everyday communication of nerve cells and eventually affect the execution of cognitive function.…”

Investigating the influence of an adjustable zoned air mattress on sleep: a multinight polysomnography study

“…A previous study using a zoned spring mattress (Verhaert et al, 2011 ) indicated that suitable support improved the sleep quality for the participants who spent most of the time in a lateral or prone posture. Zhang et al ( 2021 ) recently proposed a smart mattress that could automatically recognize the sleeping position and adjust the pressure during sleep, but it lacked the support of sleep experiments. A smart, real-time adjustable zoned air mattress was designed as part of this study.…”

Anthropometric Data Importance in Furniture Design and Marketing

“…It has been determined that overweight users are not taken into consideration in the process of designing and making furniture construction in Slovakia (Réh et al, 2019). With beds and mattresses, the implications are broader than pure furniture durability as they affect sleep quality and subsequently quality of life (Zhang et al, 2021). Therefore, the aim of the research presented in this article was to determine whether for such Slovak consumers it is possible to easily find and acquire an appropriate mattress.…”
