Pillow design and evaluation of shoulder and neck surface pressure to sleep quality

Factors that affect sleep, compression of the body as one of the factors that affect sleep. Therefore, this study is to explore the head and neck parts of the surface pressure, sleep posture change and the interaction between the pillow and shoulder pressure changes in the degree of impact on sleep quality. Proposed pillow reduction pressure innovative design, whether to enhance sleep quality. This study from the understanding of sleep during the shoulder and neck postural changes and the degree of surface pressure. Focus on observation of the results of collective law and set out the design criteria. During the experimental evaluation, the degree of compression of the shoulder and neck can be measured using the Arduino pressure sensor to understand the subjects during sleep in various parts of the muscle pressure and postural changes in pressure. Sleep quality assessment. Can be measured through the main signal of the brain waves measured by the brain waves measured in the degree of sleep in the decompression process of whether the impact of sleep quality. Watch the frequency of the brain waves Theta and Delta waves to enter the deep sleep period. To assess the mental state of subjects to do the assessment of sleep quality and the correlation between sleep quality and degree of compression. Experimental evaluation of the expected results. Sleep quality and compression degree of relevance. Through different materials to ease the shoulder with the degree of pressure. Reduce the overall shoulder and neck compression can help improve sleep quality. In this study, innovative pillow design helps to relieve head and neck surface stress and improve sleep quality.
