本文介绍一种材质识别多功能触觉传感器 ,它呈平面单一构造 ,但具有三种传感器功能。该传感器由制做在柔性绝缘薄板上的两只金属线圈构成 ,有 4个输入输出端子。当它作电感线圈使用时 ,呈感性功能 ,可以识别金属和半导体材料 ;当它看作一个平面状电容时 ,呈容性功能 ,可以识别绝缘材料 ;而当它用于控温电路时 ,该传感器呈温觉功能。由试做的传感器能识别一些典型的材料如铁、铝、铜、黄铜、橡胶、木材、有机玻璃和发泡塑料等。实验结果表明该传感器具有较好的识别能力
This article describes a material recognition multi-purpose touch sensor that has a flat, single construction but has three sensor functions. The sensor consists of two flexible metal sheets made of flexible insulation sheet, with four input and output terminals. When it is used as an inductor, it has an inductive function to recognize metal and semiconductor materials. When it is considered as a planar capacitor, it has a capacitive function to recognize the insulating material. When it is used in a temperature control circuit, The sensor is warm feeling function. The tried-and-tested sensor identifies some typical materials such as iron, aluminum, copper, brass, rubber, wood, plexiglass and foamed plastic. Experimental results show that the sensor has better recognition ability
