Medical insoles play a significant role in pressure reduction, proper stress-strain distribution, and correcting some deformities in the foot. The aim of the present research is to design and fabricate new medical insoles with universal fluid layer. After fabricating two types of insoles including flat silicone insole with shore 17 and flat silicone insole with universal fluid layer (medical silicone with shore 17 and silicone gel with shore 0), PEDAR test using one person in two standing and walking positions in three conditions comprised without the use of medical insole, using of flat medical silicone insole, and flat silicone insole with universal fluid layer was performed. These insoles were also modeled and solved in Abacus software according to the results obtained from mechanical properties testing of silicone and PEDAR test. The results of the finite element analysis showed that absorption of stress and strain in the static state by the silicone insoles with universal fluid layer was 63% and 63%, and in the dynamic state was 84% and 89% more than those obtained by the flat silicone insoles, respectively. The experimental results of the PEDAR system also showed that in the standing state, the silicone insoles with universal fluid layer and the flat silicone insoles had 58% and 30% pressure reduction, respectively, in comparison with without insole condition. Also, in the gait state, the silicone insoles with fluid layer and the flat silicone insole showed 37% and 9% pressure reduction, respectively, in comparison with without insole condition. Eventually, it was found out that the silicone insoles with fluid layer reduce plantar pressure well in comparison to the flat silicone insoles.

设计和制造具有通用流体层且具有可自动定制功能的新型医用鞋垫。

医用鞋垫在减压，正确的应力应变分布以及矫正脚部某些畸形中起着重要作用。本研究的目的是设计和制造具有通用流体层的新型医疗鞋垫。在制造出两种类型的鞋垫后，包括具有肖氏硬度17的扁平硅树脂鞋垫和具有通用流体层的平坦硅酮材料的鞋垫（具有肖氏硬度17的医用硅树脂和具有肖氏硬度0的有机硅凝胶），在三种情况下使用一个人在两个站立和行走位置进行PEDAR测试在不使用医用鞋垫的情况下，使用扁平的医用硅胶鞋垫和具有通用流体层的扁平硅胶鞋垫。这些鞋垫还根据从有机硅的机械性能测试和PEDAR测试获得的结果在Abacus软件中进行建模和求解。有限元分析的结果表明，具有通用流体层的有机硅鞋垫在静态下的应力和应变吸收比在普通状态下所获得的吸收量大63％和63％，而在动态状态下则分别高84％和89％。平面硅胶鞋垫。PEDAR系统的实验结果还表明，与不带鞋垫的情况相比，在站立状态下，具有通用流体层的硅胶鞋垫和扁平的硅胶鞋垫的压力降低分别为58％和30％。同样，在步态下，与没有鞋垫的情况相比，具有流体层的有机硅鞋垫和平坦的有机硅鞋垫的压力降低分别为37％和9％。最终，
