Research on Capacitive Flexible Tactile Sensor Based on Porous Composite Dielectric Layer
摘要
Abstract
In order to improve the sensitivity and dynamic response characteristics of the tactile sensor, con-ductive microcellular foams of GNPs/CB/SR nanocomposites were prepared with favorable electrical properties and flexibility based on foaming technology, and it was used as composite dielectric layer to design high-per-formance capacitive flexible tactile sensor. The foaming agent concentration was analyzed to investigate the in-fluence on the electrical properties of porous structure composite dielectric layer. And the microstructure and morphology of porous structure composite dielectric layer were characterized. The capacitive tactile sensing unit structure of porous structure composite dielectric layer, working mechanism and corresponding performance op-timization methods were systematically analyzed. Meanwhile, performance testing for the capacitive tactile sensing unit was conducted, and expandable tactile sensing array was designed. And the capacitive tactile sensing array information extraction system based on high-performance microprocessor STM32F103VET6 and capacitive digital converter AD7147-1 was designed to achieve real-time pressure distribution perception. The experimental results indicated that the proposed capacitive tactile sensor with porous structure composite die-lectric layer possessed good detection sensitivity and dynamic response characteristics, and could be used as robotic electronic skin to achieve high-performance tactile perception.关键词
