A see-through microphone

In this short video, we demonstrate a transparent microphone made from silver nanowire coated piezoelectric PvDF. This fun little project was a collaboration with Josh Sanz-Robinson (Advisers: Sturm,  Wagner)

The video:
(0:04)-(0:20): Vivaldi's unmistakable 'spring' is played into the microphone, one can see a small square of plastic being held in two large magnetic vices. A breadboard is visible where the piezoelectric signal is then amplified, digitized, and sent into a computer.
(0:30)-(0:42) Playback of the recorded signal, again recognizable if not maybe a little tinny. Heard laughing is Yasmin, heard talking is Josh S-R, and myself.
