Test of the piezo single axis unipolar

We tested a simple version of the piezo device in Phil's lab. We used a NI-USB DAQ 6221 and a LabView program to control the piezo.
Below you can see a photo of the setup. On the left we have the piezo stack. On the right, we have the electronic circuit with the CD/DC converter. Connections from left to right: Vout (to the piezo), red wire is +; Vcontrol (to the DAQ card), red wire is +, and Vin (to power supply) yellow wire is +.  See more on this device in the doc.

The video below shows the piezo in motion. On the left we have the life image from a CCD camara. On the right we have the front pannel of the LabView program. This was also the first time we tested this program to drive the piezo. This LabView program is designed to allow integration of the piezo with other devices, using our LabView platform for integration and automation. See more on our Software page.
