Hu increased the driving force of the piezoelectric crystal while the microscope was operating in the tapping mode to deliberately produce chaos.

An example of this is potassium sodium tartrate, which is a piezoelectric crystal that works as a transducer, both as a microphone and as a slimline loudspeaker component.
