Improvement of piezoresistive accelerometer performance

In the present paper, piezoresistive accelerometer performance is improved by the development of a suitable mathematical model. The simulation of the developed model allows selecting the best value of damping rate to minimize the measurement error to 1%. This model is validated by a series of tests carried out by computer simulation. The obtained results have showed that a suitable dumping rate can minimize measurement error of relative movement to 1 %. Using the present model, the dumping rate and precision error of the accelerometer can be improved.
