Abstract :
An acceleration sensor used to determine the vehicles speeds on the highways is developed. The sensor is able to measure the vibrational accelerations perpendicular (out-of-plane) to the asphalt surface as low as 1 mG. The sensor structure is validated with the engineering software packages: ANSYS, COVENTOR and Matlab.
