Abstract

Piezoelectric ceramic materials have an important number of applications that is continuing increasing. One of these applications is as driving element in the design of an accelerometer. They may be used in monitoring vibration for the automobile and aeroespacial industries and robotic or civil engineering. The cymbal transducer is a good candidate for accelerometer applications due to its high effective piezoelectric charge coefficients. In this work it is shown that changes in the geometry and size of the caps improve the performance of the sensor. The sensitivity of the cymbal accelerometer increases with decreasing cap size. The mechanical vibration response of the cymbal is studied and different properties, like resonant frequency, electromechanical coupling coefficient, and fastest response time are compared.
