基于EIT技术的柔性触觉传感器的设计
The Design of Flexible Tactile Sensor Based on EIT
摘要
Abstract
The rapid development of robot technology has led to new applications of soft sensors for robotic sensitive skin. In this paper we present a study on the design of flexible tactile sensor based on the piezoresitivity of a new conductive polymer which has been developed by ourselves. The conductive polymer is made by blending PDMS (polydimethylsiloxane,polydimethylsiloxane)with a small amount of multi-walled carbon nanotubes(MWCNTs) which has a high sensitivity in resistance-pressure response. The Electrical Impedance Tomography(EIT)is used to create the flexible tactile sensor. The peripheral hardware circuits based on EIT are designed and manufactured. The data obtained from hardware circuits is processed by computer. The finite element modeling and image recon⁃structue has been performed with a toolkit called EIDORS. The experiment has been carried out to successfully identify the positions of the targets in 1~3 goals when touching on the sensor surface.关键词
