| Popis: | In this paper, a numerical model to improve the pressure sensitivity of sensor has been proposed. We determine how the temperature effect the pressure sensitivity in this sensor types during the applying a supply voltage. In addition, the evolution of sensor sensitivity has been calculated as function of supply voltage, as well as, for various times, for some geometrical parameters of the sensor. It has been observed that the sensitivity is greatly affected by the rise in the supply voltage, mainly when the sensor is operated in the prolonged time. Finally, this work allows us to evaluate the reliability of sensors. Also, it permits to predict their behavior against temperature due to the application of a voltage of a bridge and to minimize this effect by optimizing the geometrical parameters of the sensor and by reducing the supply voltage. |
