XYZ Positioning Mechanism Integrated in Automated Medical Instrument Developed in Partnership with ITL

Standard or Custom Engineered Solutions when Time is Critical? The old question – standard or custom – was one of the key considerations when ITL Group decided on what precision multi-axis motion system to use in one of their latest projects. In this particular case, ITL was approached by a client with an open frame […]

Piezo Transducers, Actuators, and Motor Drive Solutions for Medical Engineering

Medical engineering and life-science disciplines have multi-faceted requirements for motion and positioning equipment: the spectrum spans from ultrasonic transducers to simple low-energy drive components to high-precision positioning systems and ultra-fast actuators for valve and pumping applications. Piezoceramic transducers and motor drives meet these needs and have a long track record of reliability and ruggedness in […]

Ultrasonic Piezo Transducers: From Welding to Medical Applications

Standard PZT and Lead-Free Piezo Ceramics Ultrasound has been used in nature for navigation above and under water. Bats and dolphins are but two species who perfected the transmission, reception, and processing over millions of years. Frequencies above 20 kHz – above the hearing range of the human ear – are labelled as ultrasound. What […]

Hexapod Robots in Laser Microsurgery Research

Laser micro-surgery can benefit from tracking and image-based methods that improve precision and safety. Advanced software together with stereo camera feedback allow for motion estimation reduce tracking errors.  A highly precise parallel kinematics motion system (Model H-824 from Physik Instrumente) with 6 degrees of freedom was used to evaluate the performance. More information is available […]

High Performance Motion Control – Systems Approach Provides Nanometer Precision for Industrial Applications

High performance motion control plays a key part in positioning and handling applications, such as those in semiconductor manufacturing, laser and materials processing, optical inspection systems, additive manufacturing or industrial digital printing. In addition to providing reliability and robustness, deterministic behavior with minimized latency, high-speed synchronization with external devices, such as lasers and cameras, is […]

Piezo Acoustics: Turning Windows into Invisible Speakers and Helping James Bond Keep Secrets

Piezo transducers can turn vibration into electric energy (“the direct piezo effect”) and electric energy into motion (“the inverse piezoelectric effect”). They are used in everyday applications from buzzers to gas igniters and in high-tech markets from medical to semiconductor applications. Typical piezo elements are made of PZT ceramics and the piezoelectric effect responsible for […]

Hexapods and Parallel Kinematics Positioning Systems FAQs

Hexapod positioners are often referred to as Stewart Platforms. A hexapod is based on a 6-axis (XYZ, Pitch, Roll, Yaw) actuator system arranged in parallel between a top and bottom platform. PI parallel kinematics (PKM) precision positioning systems have many advantages over serial kinematics stages, such as lower inertia, improved dynamics, smaller package size, and […]

Dental Biomechanics Research Based on Hexapod 6-Axis Platform

Hexapod motion and positioning platforms have traditionally been used in engineering, optics, and physics applications for their ability to provide precision motion in all degrees of freedom and flexibility based on a programmable center of rotation. As hexapods become more mainstream, applications expand into medical fields as well. Dental biomechanics deals with the interactions between […]

Patterned Force Generation — A Precise Touch in the Time Domain

Computing’s inflection points occur when new user-interface concepts enter the mainstream. The advent of the graphical user interface is one example; the touch interface, now universal on smartphones and tablets, is another. Computing is in the midst of yet another inflection with the advent of voice control, but meanwhile the haptic revolution is still unfolding. […]

Super-Resolution Optical Microscopy, Nanoscopy, and Nanopositioning Motion Control

Much has changed since the first optical microscope was designed in the late 16th century by Hans and Zaccharias Janssen, two Dutch spectacle makers. For the first time, their invention put multiple lenses to use, resulting in much higher magnifying power than a single lens could achieve. For almost 400 years optical microscopy did not […]
