Abstract

As part of the DTI programme on the development of test methods for characterisation of advanced materials, project CAM 7 Electroactive materials properties under conditions of high stress or stress rate, has the overall aim of defining and improving the measuring framework for electroactive materials which will enable them to be used with greater confidence by UK industry. Earlier reports within CAM7 have described measurement methods for piezoelectrics at high electrical stresses. This report discusses the extension of those methods to allow measurements to be carried out with superimposed mechanical stresses, and also the extended use of these methods with repeated exposure to measure the degradation of performance.
