This paper is concerned with the development of an active vibration isolation device using PZT wafers. The main task of the device is to protect vibration-sensitive instruments from hazardous environments. The device developed in this study consists of S-shaped supporters bonded with PZT wafers, passive damping materials and piezoceramic sensors that can measure the relative motion between the base and the platform. The newly developed device can produce discernible displacement thus providing a way of counteracting external disturbances. Control techniques, which can fully utilize the functions of the device, are also developed. The experimental results show that the proposed device and the control techniques are capable of isolating vibrations thus useful in protecting sensitive instruments from external vibrations.
