.This paper presents a novel type of a semi-active suspension system featuring ER(electro-theological) damper. Firstly, an ER fluid is composed and its Bingham property is tested as a function of an electric field. Governing equations of motion or the ER damper are derived by considering field-dependent yield stress, followed by the design and manufacturing through performance analysis. A semi-active suspension system is then formulated and its dynamic characteristics are evaluated via several control algorithms. It is show that the proposed method is very effective for the improvement of the vibration isolation.<br/>
