I also analyzed the impedance as a function of frequency (using the handy Analog Discover 2 USB oscilloscope), shown below. We can see the fundamental resonance a bit above 100 Hz (note: next prototype should make this lower). -<img src="img/waveforms-impedance-1.png" height=400px> +<img src="img/waveforms-impedance-1.png" height=600px> I took some high speed video to look at the deformation modes.
