Yesterday we successfully installed and tested the piezo driver at Dilson's lab, McGill University, Dep of Physiology. It was tested using Dilson's piezo actuators (which uses a piezo tube from BPO). A glass needle was attached to the piezo actuator and its tip, only a few microns in diameter, was observed with a NIKON inverted microscope at 60X. The entire device responded very well to the motion commands and its stability (keeping its position) was adequate. 

This piezo driver was assembled by Antonio. It can drive one piezo tube in 2 axis or two piezo tubes in one axis each, independently. The driver takes in an analog voltage from a DAQ card.

We have a product!

Next steps is to render the design of the driver more modular, to make it extendable to more than two axis. After, we're talking about integrating a micro-controller and to make it independent of a DAQ card, controlling it via a serial port (USB). The same modular architecture can be used to integrate the piezo drivers with valve actuators. An entire family of lab instruments can emerge from this... We'll take it one step at the time.

If you want to participate in R&D or in the commercialization effort please contact us. We're open!
