N2 - In this paper, a non-linear model is presented for a magnetostrictive force sensor and the effective parameters in the sensor are highlighted. It was found that pre-stress and bias magnetic fields are the most significant parameters. It was observed that the presented force sensor has linear behavior for an applied force range from 100 to 1700 N. Response Surface Method (RSM) was employed to analyze the sensitivity of the sensor against the effective parameters. It was found that the pre-stress and bias magnetic field and their interactions play a significant role in the sensitivity of the force sensor. Furthermore, it was manifested that the linearity can be enhanced by increasing the pre-stress. On the other hand, the sensitivity of the sensor will be sacrificed by increasing the prestress. Bias magnetic field plays the same role. The sensor’s sensitivity can be enhanced by increasing the bias magnetic field. Conversely, the sensor loses its linearity in a higher magnetic field. Therefore, there is a trade-off between sensor sensitivity and nonlinearity and both are adjustable by both, pre-stress and magnetic bias.
