| Abstract: | The effects of the physical and chemical characteristics of the conductive phase on the gauge factor(GF) of the Ru-based thick-film strain resistor has been discussed.It is experimented that there is a close correspondence between the gauge factor(GF) and the physical and chemical characteristics.The choice and optimize of thick-film material to prepare nano power, the choice and optimize of the temperature and time in the couse of solid reactivity to control the range of paticle sizes,the effective mixture of multiple paticle sizes of the conductive phase and the glass phase,charactertistics with addition can increase the gauge factor(GF) of thick film resistance. |
