A magnetic sensing system consisting of sensor and magnetic slice is introduced in this study. The position variation of the magnetic slice in magnetic field may be observed by the sensor; therefore determining the motion change of the detected device. The detailed explanation on the configuration and fundamental principle of the sensing system is described. The experimental results have proven this sensing system is able to detect the position variation of the magnetic slice effectively. It is found this wireless sensing device may be used as the torque sensor to measure the torque generated by the rotate shaft as well as the rotate rate. Due to its low cost, small volume and good environment adaptation ability, this sensing system is expected for many potential applications such as the digital-driven lathe, control system and arm rotating system in robotics etc.
