This paper reports soft actuator based tactile stimulation interfaces applicable to wearable devices. The soft actuator is prepared by multi-layered accumulation of thin electro-active polymer (EAP) films. The multi-layered actuator is designed to produce electrically-induced convex protrusive deformation, which can be dynamically programmable for wide range of tactile stimuli. The maximum vertical protrusion is and the output force is up to 255 mN. The soft actuators are embedded into the fingertip part of a glove and front part of a forearm band, respectively. We have conducted two kinds of experiments with 15 subjects. Perceived magnitudes of actuator's protrusion and vibrotactile intensity were measured with frequency of 1 Hz and 191 Hz, respectively. Analysis of the user tests shows participants perceive variation of protrusion height at the finger pad and modulation of vibration intensity through the proposed soft actuator based tactile interface.
本文报道了适用于可穿戴设备的基于软致动器的触觉刺激接口。该软致动器由多层薄电活性聚合物（EAP）薄膜堆积而成。多层致动器被设计用于产生电致凸状突出变形，这种变形可针对广泛的触觉刺激进行动态编程。最大垂直突出量为 ，输出力高达 255 毫牛。软致动器分别嵌入手套的指尖部分和前臂带的前部。我们对 15 名受试者进行了两种实验。分别以 1 赫兹和 191 赫兹的频率测量了致动器突出的感知大小和振动触觉强度。用户测试分析表明，参与者通过所提出的基于软致动器的触觉接口感知到了指垫处突出高度的变化以及振动强度的调制。
