Evaluation and design optimization of piezoresistive gauge factor of thick-film resistors

On the basis of the analysis of all the thick-film design methodologies, the authors designed a test sample on which four different length-over-width ratios of resistors were designed. They found that the length-over-width ratio will substantially affect the gauge factor in some cases, in contrast t...

Summary:On the basis of the analysis of all the thick-film design methodologies, the authors designed a test sample on which four different length-over-width ratios of resistors were designed. They found that the length-over-width ratio will substantially affect the gauge factor in some cases, in contrast to prior research. This can be modeled to generate a linear predictive model, The sensors designed on the insulator and the sensors underneath the insulator were also studied in order to simulate the multilayer hybrid technology and study the effects of insulator-resistor-substrate surface interaction. It is demonstrated that design techniques can affect the strain sensitivity of thick-film resistors.< >
