Abstract:
In order to improve the sensitivity and dynamic response characteristics of the tactile sensor, the authors prepared conductive microcellular foams of GNPs/CB/SR nanocomposites with favorable electrical properties and elasticity based on physical foaming technology, and utilized it as composite dielectric layer to design high-performance flexible capacitive tactile sensor. The foaming agent concentration was analyzed to investigate the influence 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 optimization methods were systematically analyzed. Meanwhile, the authors conducted performance testing for the capacitive tactile sensing unit, and designed expandable tactile sensing array. And the capacitive tactile sensing array information extraction system based on high-performance microprocessor STM32F103VET6 and capacitive digital converter AD7147-1 to achieve real-time pressure distribution perception. The experimental results indicate that the proposed capacitive tactile sensor with porous structure composite dielectric layer possess good detection sensitivity and dynamic characteristics, and can be used as robotic electronic skin to achieve high-performance tactile perception
