A challenge to realize multi-functional integrated microfluidic array device for real haptic information display

本研究开发了一种包括“接触力分布”和“表面纹理”在内的触觉信息显示新技术，并基于新原理制作了包含气流射流阵列和冷感显示等多种触觉显示元件的集成装置。具体的研究课题有：1)基于多射流文丘里管的冷感显示的开发；2)触觉显示压力电路的微阀开发；3)压力振动电路的设计与制作；4)多功能触觉显示的实现；5)触觉再现的系统研究。项目期间实现了各种新技术、新装置。它们将成为显示包括“接触力分布”和“表面纹理”在内的触觉信息的新技术的基础。

In this study, a new technology to display haptic information including "contact force distribution" and "surface texture" has been developed, and integrated device with various tactile display elements such as air-flow jet array and sense of cool display based on a new principle have been fabricated. The detailed topics of the study are as following, 1) Development of sense of cool display based on multi-jet venturi, 2) Microvalve development for pressure circuit for tactile display, 3) Design and fabrication of pressure vibration circuit, 4) Realization of Multi-functional tactile display, 5) Systematic research of tactile sense reproduction. During the project period, various kinds of new technology and devices have been realized. They will be a basic of the new technology to display haptic information including "contact force distribution" and "surface texture".
