精密压阻弹性体及力敏传感器阵列
Precious Piezoresistance Elastomer and Pressure Sensitive Sensor Arrays
摘要
Abstract
Ruthenium nanoparticles, fabricated by using polyol method were thermall oxided for yielding ruthenium oxide nanocrystals. By mixing the nanoparticles of nanosize ruthenium and its oxide with silicone rubber and vulcanization, the composite exhibits excellent piezoresistant sensitivity and reproducibility. The measurements of piezoresistance on various size electrodes show that the material has a stable and repeat-able load sensitive resistance variation above size limit of millimeter. The electrode arrays and electronic circuits for the measurement of planar stress distribution have been fabricated. The piezoresistance and relaxation curves for the reproducing load on the elements were fitting by measuring the piezoresistance and resistance relaxation plots. The load on the elements was corrected and the load distribution on the arrays was measured. The results show that the material can satisfy the minimizing requirements at certain size scale for the application as integrated stress sensor arrays based on piezoresistance elastomer. Using this material,the visualization of static or quasi-dynamic load distribution can be achieved at millimeter scale.关键词
