Abstract

In the fabrication process of thermo-resistive sensors, the dynamic response of a sensor is a very important feature to be noted. The dynamic characterization of a sensor reflects his electric performance when submitted to power variations. By measuring these power variations, it is possible to evaluate some of the sensor´s thermoelectric properties, and so optimize its physic configuration in the fabrication process and its subsequent use in specific applications. In this paper, the influence of the micromachined thermo-resistive sensors substrate in the determination of its thermal time constant is evaluated
