Conductive mechanism and its mathematical model of thick-film strain resistors

Some thick-film resistors base on Bi/sub 2/Ru/sub 2/O/sub 7/ were evaluated. The resistors are made by screen-printing thick film paste on Al/sub 2/O/sub 3/ substrates. After printing and drying, the thick-film pastes are fired in a belt furnace. We discuss the conduction mechanism and a strain sens...

Description
Summary:Some thick-film resistors base on Bi/sub 2/Ru/sub 2/O/sub 7/ were evaluated. The resistors are made by screen-printing thick film paste on Al/sub 2/O/sub 3/ substrates. After printing and drying, the thick-film pastes are fired in a belt furnace. We discuss the conduction mechanism and a strain sensitive mathematical model of thick-film resistors through calculating and taking the measurements of the gauge factor (GF). We also interpreted the phenomenon through the strain sensitive model, and explained the strain sensitive phenomenon, such as the GF mounts up with the barrier height's augmention.
