About 50 projects within the following topics will be presented:

Adaptive Optics

  • Smart Optics Systems: The field of smart optics systems is characterized by the use of deformable mirrors, lenses and wavefront sensors and intelligent image processing to enhance in real time the image quality of scientific observation equipment. A typical example of a smart optics system is an adaptive optics system where a deformable mirror is controlled such that wavefront distortions in a light beam are suppressed,resulting in a residual wavefront error that is measured by a wavefront sensor.

  • Optical Element Curvature Manipulator

  • Adaptive Optics and Metrology: Present the progress on two research projects. The first project is about a contactless actuation method for introducing of for instance mirrors adaptive optics. The second project is about metrology methods to verify the induced deformations.

Automotive / Vehicle Mechatronics

  • X-Car moving base simulator: The X-Car is used to test the driver behaviour under various driving conditions. Tests can be performed, for instance, to measure the driver's body movements under extreme steering manoeuvres. These tests are of importance when developing active safety systems where the ECU intervenes instead of the driver, like the ESP. Purpose of this demo is to show the potentials of this high-end automotive simulator for performing the former research.

  • Load Based Vehicle Dynamic Control: The BMW is used to develop a novel family of vehicle dynamic control systems: load-based control systems. A new sensing technology developed by SKF enables the direct measurement of tire forces; by using that information safer and more performing vehicle dynamics control systems can be implemented.

  • Adaptation of hybrid five-phase ABS algorithms for experimental validation: The Anti-lock Braking System (ABS) is the most important active safety system for passenger cars. Current ABS are often based on heuristics.
    A theoretical five-phase hybrid algorithm based on wheel deceleration offers stability proof and performance analysis for simple model, but shows problems in practical implementation.

Bio Medical Instruments

  • Android Neural Stimulator: Neural stimulation is expected to become a major treatment method for a wide variety of diseases. In order to improve the efficiency and patient comfort, a new architecture is proposed. A prototype is presented which shows the endless waveform capabilities, while it is easily controlled using an Android Smartphone.

  • Parallel Robot for Haptic: Since parallel robot combine light weight and high stiffness, they are increasingly used as haptic devices. This demo shows the prototype of a new parallel robot architecture used as a haptic device.

  • Optimization of arthroscopic view: Based on experimental research and theory on fluid dynamics, the Department of BioMechanical Engineering develops both new hard- and software to optimize arthroscopic views.

  • Simulators for arthroscopy: Minimally invasive surgery in joints (arthroscopy) has proven to be beneficial for patients. In contrast to the increasing advances in arthroscopic technology, the traditional training methods of surgical skills have not been adjusted accordingly. This might not only cause unnecessary training costs, but also risk patient safety.The Department of BioMechanical Engineering develops a simulator (PASSPORT) that speeds up the training process significantly within a safe learning environment, while simultaneously serves as testing platform for new instruments.

  • Orthopedic devices for surgical alignment of small bones: Small bones are located in the foot, ankle and wrist. Determination of the extend of pathologic conditions, such as flat feet or correct realignment during the operation is difficult for these small bones. Physical examination at the daycare centre is unreliable as the surrounding soft tissue is obstructing. Radiographs are of no help, because bones are overlapping, and the patient is differently positioned in the operating room. The Department of BioMechanical Engineering facilitates a quantitative and reliable diagnosis of deficiencies or surgical verification of bony realignment in an intuitive manner.

  • TrEndo;Tracking system for Endoscopy: The TrEndo tracking system is designed for the resident surgeons to improve their basic skills in a simulated environment with real force feedback. Combined with a custom made force platform the system allows for both motion and force tracking.

  • Force-Platform; Visual force feedback in Laparoscopy: The FORCE PLATE is designed for the resident surgeons to improve their tissue handling skills in a clean and safe environment, When box trainers and simulators are equipped with force sensing technology, information about interaction force and torque can be used to train delicate tasks that require adequate force control.

  • Isolator Systems for laparoscopic surgery: To guarantee high sterility levels during minimally invasive procedures, a novel new system is currently being developed in cooperation with the Delft University of Technology and the Leiden University Medical Center. This Isolator System for Minimally Invasive Surgery (MIS) consist of a special trocar (guiding tube) that protects the instrument, trocar and incision against harmful microorganism.

  • SB-MEMS; Statically balanced micro mechanisms:

  • SBCM's: Statically balanced compliant mechanisms: Compliant mechanisms take up elastic potential energy during motion due to their deformation. This ‘loss’ is often regarded as a ‘necessary evil’. However, the elastic energy is not lost, it is stored. Consequently, its effect on the input-output behavior can be eliminated by static balancing by another elastic balancing part.

  • Optimization of breast cancer detection: Since 1997, women from 50 years old get the opportunity to participate in a mammographic breast screening program every second year. To optimise this screening process, this studie is done to verify the possibilities of breast cancer detection on the hand of the mechanical behaviour of healthy breast tissue in comparison with cancerous breast tissue.

  • Nanomechanical Silicon Cantilevers: Silicon nanocantilevers are widely used in sensing and actuating applications. For reliable design of such devices, a thorough knowledge of the mechanical properties of these nanostructures is of vital importance. decreasing the size of the nanocantilevers causes the mechanical behavior and especially the elastic behavior to deviate from the bulk value, known as “size-dependence'' phenomenon.

  • Gecko-effect based Micro-conveyor: Micro-conveyors are important elements for microsystems technology, because they allow improving the performance of micro-actuators by reaching long, total strokes. Unfortunately, current solutions have low accuracy and efficiency at high speed,
    principally caused by the inertia. The adhesive strength of Gecko feet, transportation by motile Cilia or controlled motion of Millipede can inspire improvements of key
    parameters of a micro-conveyor

An external magnetic field applied to the system draws the modified chips to the alignment profiles on the tool. To prevent stiction problems that might occur during the alignment process, a suspension media (an air neutral air profile) is introduced to the system.

  • Lightweight high energy density micro-actuator: Recent years show a trend in scaling down Micro Aearial Vehicles (MAVs). Traditional fixed wings are not suitable at sizes below 10[cm]. The usage of flapping wings offers a solution.
    The design of such systems brings forward new problems regarding energy and system behavior, related to scaling laws. The laws of physics act differently at macro- and micro- scale.A new means of energy storage and energy conversion into mechanical energy are therefore required.
