Piezoelectric Fans Could Be The New Way To Cool

Piezo fans work on a simple principle. The piezo fan has a flexible blade, typically made of mylar, that is set into motion by a piezoceramic bending element. This bending element functions due to an ultra low power oscillating current of electricity. The electric field causes the piezoceramic to elongate, which bends the blade back and forth. The rapid flapping action produced is much like that of a humming birdís wing, and creates an enormous amount of cooling capacity.

I wonder if the noise level could be reduced when you no longer have 1 big flow of air, but rather several such fans inside a heatsink moving a little air.
