摘　　要：以质量分数3%和2%的炭黑/碳纳米管填充硅橡胶为力敏复合导电材料,提出了一种微圆顶阵列结构的柔性触觉传感器。阐述了微圆顶阵列结构触觉传感器的结构特点、制备流程及微观表征,并结合ANSYS有限元分析软件分析其触觉感知机理。研究该微圆顶阵列结构柔性触觉传感单元的力敏特性,并将其应用于足底压力分布感知。测试结果表明,该微圆顶阵列结构柔性触觉传感器具备良好的力敏特性和穿戴舒适性,为柔性可穿戴触觉传感器提供了一种设计方案。The silicone rubber filled with mass fraction of 3% carbon and 2% of carbon nanotubes was used as the force sensitive conductive composite materials. A flexible tactile sensor with microdome array structures is proposed in this paper. The structure characteristics, fabrication process and micro characterization of the tactile sensor with microdome array structures are researched, and the tactile perception mechanism is also revealed with ANSYS finite element analysis software. The force sensitive characteristic of the microdome array structures flexible tactile is studied and the application of plantar pressure distribution perception is illustrated. The experimental results indicate that the microdome array structures flexible tactile has good force-sensitive property and wearing comfort, and it provides a design proposal for flexible wearable tactile sensor.
