Electromagnetic and Piezoelectric Transducers

Chapter
Part of the Solid Mechanics and Its Applications book series (SMIA, volume 246)

Abstract

This chapter analyzes the constitutive equations of discrete electromechanical transducers. It begins with the voice coil transducer which can be used as sensor as well as actuator; it is followed by applications to modelling of the proof-mass actuator and the geophone sensor. The single axis gyrostabilizer is briefly discussed next. The second part of the chapter is devoted to the constitutive equations and the modelling of a discrete, single axis piezoelectric transducer. The physical meaning of the electromechanical coupling factor is discussed as well as its measurement. The chapter concludes with a short list of references and a set of problems.
