Hi Everybody! My name is Tom, and I'm a student at Penn State in Electrical Engineering. I was wondering if anybody knows anything about piezoelectric materials. What I want to know is if it's possible to draw out an element, like a strand of hair, of piezoelectric material (by any process) to obtain a "wire" through which you could pass a (small) current causing it to move. I know that piezos VIBRATE when they get an AC current, but if you gave it a DC current, would it "grow" (or "shrink") in size (and stay there)? If anybody has information on this or knows where (or from whom) I can get such information, I'd really appreciate it. Thanx! - Tom Rusnock TJR122@PSUVM.PSU.EDU
