Research of Tactile Display Technology in Telerobotic

文章在介绍国内外触觉显示领域研究的基础上,针对人类FAI和FAII触觉神经末梢的频率响应特性和感受深度阈,利用Moonie型压电陶瓷-金属复合体结构的逆压电致伸效应,研制了3×3像素规模的压电振动式触觉显示器。以几何图形平均识别成功率作为评价衡量触觉显示质量的指标,分析了驱动频率与触觉感受的关系。最后指出PZT触觉显示器走向实用化所必须研究克服的问题。

Based on the effort in tactile display field is intro-duced in some detail,3×3pixels piezoelectric vibrancy tactile display is produced aim at human FAI and FAII tactile nerve's frequency response characteristics and sense depth threshold,using converse piezoelectric characteristic of Moonie piezoelec-tric ceramics-metal composite.Regarding Identification geome-try graphics average success rate as guideline which expresses tactile display's quality.The connection between tactile sense and drive frequency is analysed.Some questions which restrict PZT tactile display to be utilized practically,are pointed out fi-nally.
