RE: "Mechanical movement dissipates the energy as heat."

Hi Geoff,

With respect to "...help explain absorption of acoustic energy and electromagnetic radiation in crystal structures, the peizolectric effect is not one of them."

Since the piezoelectric effect describes the coupling between the E field and distortion of the crystal lattice, how could it fail to be one of them?

If I may take a shot at answering the question you posed for Stu, crystals actually change their physical dimensions when a field is applied. The crystals themselves are very efficient electro-mechanical transducers (hence their high Q) but if they are mounted in a lossy medium they transfer some of that mechanical energy to it which ends up as heat. Thus the answer is 'both'.

Rick

PS: I don't have a clue how effective they are in this application.
