Precious Piezoresistant Elastomer and Pressure Sensitive Sensor Arrays

Ruthenium nanoparticles fabricated using polyol method were thermal oxided, yielding ruthenium oxide nanocrystals. The mixture of ruthenium oxide and ruthenium nanoparticles have moderate aggregation behavior. After mixing the nanoparticles 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 certain scale invariance above size limit of minimeter. Nvariance, which means the microscale application can be fulfil above this size, such as integrated strss measurement arrays based on piezoelastomer. The electrode arrays for the measurement of planar stress distribution have been fabricated. The electronic device and supporting software havealso been composed for dynamic tactile sensor array. The measurements show that the static and dynamic load distribution and its visulization on the surface of elastomer can be realized by acquired and processed within microseconds, based on the piezoresistant response of individual sensing element. The repeatability and quantity of this array can satisfy the basic requirments of ergonomics devices
