New Ultrasonic Piezoelectric Actuator for Nanopositioning (436 KB) Physik Instrumente (PI) has developed a new type of ultrasonic piezoelectric actuator which can be used effectively in direct linear drives. The actuators are of simple construction and allow design of very compact, fast and inexpensive micropositioning systems. |

Hybrid Actuators for Large Travel Range and Extreme High Resolution (840 KB) Traditional motor drives can be used for large movements, but the resolution is far from the requirements for nanotechnology. The paper describes new hybrid systems designs such as the combination of piezoelectric and motorized systems with a long travel range and extremely high resolution. |

Sub-Nanometer Precision Hybrid Positioning Systems for Vertical Inspection Tools in Nanotechnology and Semiconductors (264 KB) This paper describes a new adaptronic product design, specially prepared for vertical motion of optics for inspection or profiling systems. Simultaneous control of piezo flexure actuators and motorized drives provides inches of travel with nanometer to subnanometer resolution. |

Parallel-Kinematic 6D Alignment System with Sub-Micrometer Accuracy (280 KB) PI’s hexapod parallel kinematic structures have been employed in ultra-precise positioning and alignment applications for a decade. Examples are precision alignment of satellite antennas, control of secondary mirrors (astronomical telescopes) and industrial handling and micromachining systems. |

Reliability & Lifetime of Multilayer Piezo Actuators. The paper describes the development and lifetime tests of ceramic encapsulated actuators in comparision with conventional polymer coated piezo actuators. Dynamic operation with a new internal electrode design for stress reduction as well as special external electrodes for high-current applications are discussed. |

Enhancing the Analog-Output Resolution of the Latest NI DAQ Hardware (572 KB) The latest generation of National Instruments analog I/O hardware is capable of extraordinary speeds and up to 16-bit analog output (AO) resolution. A newlypatented i technology, originally developed for ultrademanding nanopositioning applications, allows users to extend their digital-to-analog (DAC) resolution well beyond 16 bits. An example application generates waveforms with amplitudes of 0.0001V, well below one least-significant-bit (LSB) for the hardware – in fact, approaching 24 bits. |

| • | Precision piezo motors and actuators: Sterile, non-magnetic solutions for medical device design. Factored into a medical device's product development are considerations such as size of the equipment, speed of operation, heat generation, portability, handling of static or kinetic loads, power sources, measuring systems, vacuum and nonmagnetic requirements, sensors, machine controls, component part wear and diagnostics. A key impetus for medical and bioresearch companies to engage upon these involved product development cycles is the opportunity to capitalize on advances in technology for the manufacture of better operating, lower cost and more efficient equipment and devices. |

Interfacing Fast Nanopositioners to Track-Following Servos (336 KB) The combination of PI’ s E-712 controller and National Instruments’ FPGA-based automation hardware and software form a powerful, flexible platform for integration engineers facing an onslaught of new head test requirements, including higher throughputs and potential production integration of track-following servos on the spinstand. By combining unmatched responsiveness in conventional closed-loop nanopositioning with new feedforward capability which facilitates integration into external tracking servos, E-712 helps preserve capital investments by eliminating obsolescence due to advancing production-test needs. |

| • | Nanoindentation: Measuring in the sub-nanometer range. Nanoindentation is derived from the classical hardness test but is carried out on a much smaller scale. It can be used to determine the hardness of thin layers as well as material properties such as elasticity, stiffness, plasticity, and tensile strength, or fracture toughness of small objects and microsystems in fields such as biotechnology. These measurements involve applying a small force to a sample using a sharp probe and measuring the resultant penetration depth. |
