Claims

C1strongest claim

Extra components in series to non-ferroelectric capacitance can cause apparent ferroelectric D-E hysteresis loops even with the double-wave method (DWM).

C2weakest assumption

That the simple circuit models accurately capture the dominant artifacts present in real experimental setups reported in the literature, and that the microphone detects only the inverse piezoelectric strain without introducing its own electrical or mechanical artifacts.

C3one line summary

Series non-ferroelectric capacitance creates apparent ferroelectric D-E loops, and a simple microphone method reveals true piezoelectric S-E loops in a commercial capacitor.
