Burleigh’s linear low-noise electronics and cables are fully shielded and carefully grounded to produce negligible interference of your recordings. 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.
Three full rotations of each potentiometer knob corresponds to the full range of the PZT travel. Each linear stage, using cross roller bearings, provides 25 mm of coarse travel through 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. 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.
Components and Operational Features. The result of applying this control technique was a reduction of the micropositioner’s decay time from over 1 ms to under 0. Smart Materials and Structures. Sign up for new issue notifications.
To see an animation of the PCS click here. Self-sensing actuation is a control technique that can be applied to many smart materials including piezoceramics. 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.

When controlled by Burleigh’s drive electronics and ergonomic control brleigh, extremely precise, fast, stiff and stable positioning is easily achieved. Get permission to re-use this article. 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.
A major contributor to the success of this research was the insertion of a nonlinear element in the self-sensing bridge which negated the burlegih effects of the PZT stack thus enabling an increase in the self-sensing signal-to-noise ratio. The result of applying this control technique was a reduction of the micropositioner’s decay time from over 1 ms to under 0.

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.
Only Burleigh piezoelectric micromanipulators provide this capability because we use the solid-state stability of piezoelectric Ozt technology. The research presented is concerned with the feasibility of applying this technique to a soft PZT stacked actuator used as a micropositioner.
