Development ofon-demand clothes and related manufacturing method for the aged and the handicaps health

这是一项考虑到人的健康状况和日常生活习惯的纺织棒和相关生产技术的开发研究，以保持老年人的健康。最近，卧床不起的老人的焚烧在日本成为一个问题，因此，按需提供床上用品将有助于解决这一问题。为此，我们研究了床上用品的力学性能与睡眠舒适性之间的关系，以及按需生产床上用品的睡姿预测方法。主要结果在允许的情况下砍掉。为了建立舒适床垫的设计指标，我们采用脑电波、POMS等心理生理学测量方法，研究了床垫刚性与睡眠舒适性的关系。结果是，随着床垫僵硬程度的提高，睡眠质量会变得更好。可能是因为高刚性床垫能够保持适当的睡眠姿势。也有研究表明，随着床垫硬度的增加，睡眠深度变深，睡眠周期变长。2)为了辅助或按需设计床上用品，我们开发了睡眠姿势模拟器。仿真中采用有限元模型作为床垫模型，采用由弹性关节和刚体组成的刚体连杆模型作为人体模型。因此，虽然模拟床上压力分布的误差很大，但可以精确地预测睡眠姿势。由此可见，利用机械模拟技术生产按需床上用品是不远的事情。

This is a study regarding development of textile goads and related production technology which consider person's health condition and daily life habits in order to keep health for the aged Recently incensement of bedridden old people has become a problem in Japan, therefore, on-demand bedclothes will contribute to the solution of the problem. For this purpose, we have investigated the relationship between sleeping comfort and mechanical properties of bedclothes, and the prediction method of sleeping pose for on-demand bedclothes production. Main results axe as allows. D In order to develop an index for design of comfortable bed mattress, we have investigated the relationship between bed mattress rigidity and sleeping comfort by using psychophysiological measurements such as brain wave, POMS, and so on. As a result it has become clear that sleep quality tends to become good as mattress rigidity goes up. Probably, the reason is that high rigid mattress is able to keep sleeping pose proper It has also been shown that sleep depth become deep and sleep cycle become long as mattress rigidity goes up.2) We have developed the sleeping pose simulator in order to assist or-demand bedclothes design. Finite element model has been used as a mattress model, and rigid body link model that consists of elastic joint and rigid body has been used as human body model in the simulation. As a result, although an error of simulated pressure distribution on bed was large, it has become possible to predict the sleeping pose precisely. Therefore it has been shown that on-demand bedclothes production by using mechanical simulation will be achieved in the near future.
