The design and fabrication of a rolled dielectric elastomer actuator is described and the parametric dependence of the displacement and blocked force on the actuator geometry, elastomer layer thickness, voltage, and number of turns is analyzed. Combinations of different elastomers and carbon nanotube electrodes are investigated and optimized to meet performance characteristics appropriate to tactile display applications, namely operation up to 200 Hz with a combination of a 1 N blocked force and free displacement of 1 mm, all within a volume of less than 1 cm³. Lives in excess of 50 000 cycles have been obtained. Key to meeting these objectives is control of the multilayering fabrication process, the carbon nanotube electrode concentration, the selection of a soft elastomer with low viscous losses, and a proof‐testing procedure for enhancing life cycle reliability.

紧凑型介电弹性直线执行器

描述了轧制介电弹性体致动器的设计和制造，并分析了位移和阻塞力对致动器几何形状，弹性体层厚度，电压和匝数的参数依赖性。对不同弹性体和碳纳米管电极的组合进行了研究和优化，以满足触觉显示应用的性能要求，即在200 Hz的频率下运行，并结合了1 N的阻挡力和1 mm的自由位移，所有这些体积均小于大于1厘米³。已获得超过5万个周期的生命。达到这些目标的关键是控制多层制造过程，碳纳米管电极浓度，选择具有低粘性损失的软弹性体，以及提高寿命周期可靠性的验证测试程序。
