In this study, our research focuses on the suspension structure of the micro accelerometer. In order to achieve optimal results we explore various parameters in all aspects to understand its influences on spring coefficient, expecting the higher micro-accelerometer's sensitivity as well as the deviation of the structure be reduced accordingly. This paper presents a new “point symmetrical” suspension configuration, it remains the same spring coefficient of two plane axes even if disturbed by the size deviations from process, and thus keeps equal sensitivity of two axes, reducing the error of the electrical signals. This paper also proposes a new “coil suspension structure”, it compares with the most commonly used serpentine spring through the finite element analysis software ANSYS® and then analyzes the pros and cons of two springs with point symmetrical configuration.
