BURLEIGH PZT DRIVER

It involves extracting a sensing signal from the actuating material by use of a bridge circuit, then properly feeding this signal back to improve the actuator’s performance. The result of applying this control technique was a reduction of the micropositioner’s decay time from over 1 ms to under 0. Only Burleigh piezoelectric micromanipulators provide this capability because we use the solid-state stability of piezoelectric PZT technology. Components and Operational Features.

Self-sensing control as applied to a PZT stack actuator used as a micropositioner

Two pivot stages allow the entire micromanipulator assembly to be rotated forward. Only Burleigh piezoelectric micromanipulators provide this capability because we use the solid-state stability of piezoelectric PZT technology.

Burleigh’s linear low-noise pat and cables are fully shielded and carefully grounded to produce negligible interference of your recordings. Each linear stage, using cross roller bearings, provides 25 mm of coarse travel bureigh a 32 thread per inch lead screw as well as a choice of or microns of PZT travel and 60 nm resolution through a special PZT flexure assembly. No other micromanipulator has inherently lower drift than a Burleigh Micromanipulator. Smart Materials and Structures.

The power supply can be shared by two micromanipulator systems to minimize cost and space consumption when multiple manipulators are required on the same microscope. Smart Materials and StructuresVolume 3Number 2.

When external thermal changes are considered, a Burleigh system contributes the same or less thermal position drift than other components such as the microscope, mounting structure and headstage.

Total Control in Patch Clamp Micromanipulation Total control means your fingertip commands are instantly and precisely converted to smooth and predictable pipette motion without drift. Buy this article in print. Self-sensing actuation is a control technique that can be applied to many smart materials including piezoceramics.

The research presented is concerned with the feasibility of applying this technique to a soft PZT stacked actuator used as a micropositioner.

L Jones et al Smart Mater. The result of applying this control technique was a reduction of the micropositioner’s decay time from over 1 zpt to under 0. A major contributor to the success of this research was the insertion of a nonlinear element in the self-sensing bridge which negated the nonlinear effects of the PZT stack thus enabling an increase in the self-sensing signal-to-noise ratio.

The research presented is concerned with the feasibility of applying this technique to a soft PZT stacked actuator used as a micropositioner.

With proper temperature control, pipette drift of less than one micrometer per hour can be achieved. Smart Materials and Structures.

Three full rotations of each potentiometer knob corresponds to the full range of the PZT travel.
