Abstract

A capacitance type dilatometer has been constructed which is capable of resolving low frequency AC linear displacements of 10~ meter (O.OOlA) and can be used for the direct measurement of piezoelectric and electro-strictive deformation. Using the DC servo stabilization of the sensing element the mode of sensing the capacitance change generated by the crystal deformation has been radically improved. Some experimental data are given of piezoelectric and electrostrictive crystals and ceramics which have been measured by the established instrument.
