4. Clearly, the use of strain gauges would be very difficult. They have been used to measure the strain perpendicular to the polar direction, but their general usage would require specific sample configurations which need not be compatible with theoretical requirements.
5. The composition of PZT 65∕35 is Pb0.99Nb0.02(Zr0.65Ti0.35)0.98O3.
