THE NON-LINEARITY OF PIEZOELECTRIC FORCE TRANSDUCERS AND THEIR ANALYTICAL MODELLING

• Abstract:

  This contribution deals with possible reasons for the non-linear behaviour of piezoelectric force transducers, previously unknown.
  Possible reasons are interactions between isotropic elements such as force introduction and the anisotropic piezoelectric sensor element, geometrical non-linearities of the force transducer and non-linearities of the piezoelectric material.
  This paper discusses the influence of geometrical nonlinearities. A theory for analytical modelling of piezoelectric force transducers is developed and presented.
