Abstract :
The potentialities of 0.1PMN-0.1PT ceramics for active vibration control were investigated. Consequently, the ceramic behavior as sensor and actuator were characterized. The dielectric and electromechanical responses have been measured, at room temperature for different compressive stresses, by applying a sinusoidal signal of variable amplitude and frequency in addition to a DC electric field (0.6 kV/mm). The resulting behavior is very well described in terms of hyperbolic tangent formulations which moreover allow to take into account the hysteresis of the curves
