We have developed a nano vibration device for the use of cell culture to study the effects of nano vibration on cell functions. The device consists of a vibration driving unit with a piezoelectric actuator and a culture dish setting. The vibration driving unit supports the culture dish setting at one side and the other side of the setting is the free end, like a cantilever beam. The culture dish setting vibrates horizontally and it is supported vertically by four pins. We have analyzed the vibration characteristics of the device in X, Y and Z directions using an FFT analyzer. From this study, we found out that the culture dish setting was vibrating not only in X direction as we meant but also in Y and Z directions. Also, we found out that vibration amplitude of the culture dish setting in Z direction at the vibration driving unit was about twice as big as that of in X direction. This was caused by the pins touching the culture dish setting at the free end side, which worked as the fulcrum of the principle of leverage.
