摘　　要：目前国内外关于仿生皮肤模型的研究主要集中在模拟人体皮肤触力感知功能、皮肤紧密接触类物质特性测试用皮肤以及模拟出汗的单层皮肤等方面,现有的研究无法真实模拟人体皮肤出汗与温度调节的功能。针对这一问题,提出了具有热源层、汗源层及表皮层的三层仿生皮肤,研究了仿生皮肤的温度及出汗控制系统。采用模糊PID控制方法实现了皮肤内核的温度控制,通过表皮温度反馈及汗源、微量柱塞泵等组成的出汗微循环系统,控制仿生皮肤出小汗、出大汗,通过汗液蒸发降温实现了表皮温度的调节。进行了内核温度控制及表皮温度调节实验,结果表明:内核温度被控制在(36.8±0.1)℃,表皮温度自稳定在(33.5±0.3)℃,仿生皮肤能够出汗将升高的表皮温度调节回(33.5±0.3)℃。研究的仿生皮肤可应用于纺织品的红外管理特性测试,模拟皮肤、纺织品及外界环境形成的微循环系统。At present, the research on bionic skin model mainly focuses on the simulating of contact force perception of human skin, the skin model for testing the properties of substances in close contact with skin, and the single layer skin that simply simulates sweating. However, the existing methods cannot truly simulate the functions of human skin sweating and the temperature regulation. In order to solve this problem, a three-layer bionic skin with a heat source layer, a sweat source layer and an epidermal layer was proposed, and the temperature and sweating control system of bionic skin were studied. The temperature of skin core was controlled by fuzzy PID control method. Through the temperature feedback of the epidermal layer and the microcirculation sweating system composed of a sweat source and a micro plunger pump, the small and large amounts of sweating of bionic skin were controlled, and the temperature of the epidermal layer was regulated by the cooling effect of sweat evaporation. The experiments of core temperature control and the temperature regulation of the epidermal layer were carried out. The results showed that the core temperature was controlled at(36.8±1)℃ and the epidermal layer temperature was self stabilized at(33.5±0.3)℃. Therefore, the bionic skin could regulate the increased temperature of the epidermal layer back to(33.5±0.3)℃ through sweating. The bionic skin can be applied to measuring the infrared management properties of textiles and simulate the microcirculation system composed of skin, textiles and external environment.
