Abstract
Piezo-induced surface vibrations in solids with nanometer amplitude are detected and analyzed. The vibrations are excited by the piezo element using a PZT component, which attached to the target material and controlled by a signal generator. The detections of such vibrations are carried out using the atomic force probe (AFP). The AFP is a very sensitive instrument utilizing a nano-tip connected to a cantilever to detect vibrations through an interaction of atomic force between the tip and the target surface with sub-nanometer resolution, about 30 times more precise than the piezoelectric sensor for the same signal detection. The glass material has been chosen as the target solid. The enhancement effect of the vibrations in the glass slice around resonance frequency is confirmed, the maximum amplitude appears at 7.4 kHz. The piezo-induced vibration will be employed in our future research for developing piezo-induced and laser-induced surface acoustic wave (SAW) motor.
