触觉显示器是帮助人通过触觉与机器进行交互的重要工具。本文提出了一种基于介质弹性体驱动器（DEA）的多阵列触觉显示装置。该装置采用触点与致动器之间的液体耦合作为力的传递。其设计旨在确保用户在接触人体皮肤时的触摸舒适性和操作安全性。详细阐述了其工作原理，并给出了系统的设计分析.触觉显示器在3-10 Hz时的位移约为240-120 μ m，满足模拟默克尔细胞和迈斯纳小体的频率要求，模拟指尖的力超过40 mN。此外，一个专门的制造方法和性能测量进行了说明。(C)2013爱思唯尔有限公司版权所有。
The tactile display is an important tool to help the human interact with machines by using feels of touch. In this paper, we present a multiply arrayed tactile display device with Dielectric Elastomer Actuator (DEA). The device employs the liquid coupling between the touch spot and the actuator as the transmission of force. It is designed to ensure the comfort of touch and the safety of operation for the users while contacting with the human skin. The operating principle is explained in details, and a systematic design analysis is given. The displacements of tactile display is about 240-120 mu m at 3-10 Hz, which satisfies the frequency requirements for simulating the Merkel cells as well as the Meissner corpuscles and the force is over 40 mN to simulate the finger tip. In addition, a dedicated fabrication method and performance measurements are explained. (C) 2013 Elsevier B.V. All rights reserved.
