Notice of Removal: Performance evaluation and compression of some actuators and sensors piezoelectric elements

This paper describes three types of piezoelectric structures that can be used as an actuator and as a sensor. These types are the Bender Element, the Plate Transducer and the Trigger-Accelerometer. Variations in usage, the internal structure and the direction of polarization are explained in order to understand the differences between the types and the responses of the piezoelectric structures. Among the many methods that are used for analyzing and building the transfer function of piezoelectric structures, the lumped parameter model was chosen as the method of analysis. This method proved very active in analyzing the effects of the internal parameters such as the dimensions of the piezoelectric structure and the elastic constant for the output response. In addition, after the transfer functions of the actuator and the sensor were built, the effect of the input signal types to the actuator and the sensor, such as the sine wave and pulse were analyzed. Finally, the results that were obtained, were compared with other previous works, and the results were very close.
