A new method for jerk detection (derivative of acceleration) is proposed. By using a 2 degrees of freedom (DOF) model with viscous coupling, we measure jerk directly as a position change in mass without differential circuit. Analysis by numerical formulas show the principle of the proposed jerk detection and simulation results show suitable parameters such as viscosity, mass ratio, and spring coefficient ratio for jerk detection. We also propose a micro jerk sensor based on the micro electro mechanical system (MEMS). Results of analysis show that the microstructure is suitable for the proposed viscous coupling.
