摘要： Present invention involves a seal means suitable to replace the classic seals. For instance the seal means of present invention can be a liquid seal ring (7) to replace the classic rubber seal rings. Such is liquid O-ring can be adapted to resists the actuation pressure relying on surface tension forces. Such liquid O-rings can also be linked in series, hereby increasing the maximum seal pressure. In a preferred embodiment the seal means of present invention comprises two major components, a surface tension seal (7) and a pressure divider (4). The pressure divider will comprise a system that generates a pressure drop. Such pressure divider can be located before the surface tension seal and perform the first pressure drop. The combination of these two systems has the advantage that the surface tension seal is able to reduce the leakage to zero or essentially zero and that the pressure divider is able to perform a large pressure drop. Nevertheless, the surface tension seal can also create a considerable pressure drop. This means that in applications where the seal pressure of the surface tension seal is not exceeded, the pressure divider can be omitted. However, omitting the pressure divider will always result in tighter tolerances when manufacturing the seal.

摘要： Laser interferometers and high-quality linear encoders both are competitive linear measurement systems used in high-precision machines. Plane laser interferometry allows measuring to a target that moves perpendicular to the measurement direction and to set up the laser beam in line with the functional point. In this way, a stacking of measurement systems can be avoided and a measurement configuration complying with the Abbe principle can be configured. On the other hand, laser interferometry is known to be sensitive to environmental changes. High-quality linear scales are used as an alternative. A disadvantage of linear scales is that the target is only allowed to move along the measurement axis. For targets translating in more than one direction with a range over several millimeters, this leads to a simple stacking of several linear scales together with the supporting slides. This indirect way of measuring introduces errors and partially destroys the accuracy provided by modern linear scales. This patent describes a measurement concept based on linear scales, which combines the stability to environmental changes, typical for linear scales, with the ability to measure to a target that moves also in a direction perpendicular to the measurement axis, typical for plane mirror laser interferometry. The measurement concept is especially interesting for multi-axis machines where a stable and homogeneous atmosphere cannot be guarantied and where measurements should be done during motion.

摘要： A piezoelectric motor has a stator module 1, comprising two pairs of piezoelectric actuators Ia, Ib and 2a, 2b inside this stator module. The stator module is fixed by a central fixing point (A). The piezoelectric actuators 1a, 1b, 2a, 2b are connected to the stator module via flexible or biasing elements 3, such as for instance hinges, for instance elastic hinges. The stator module 1 comprises a tuning mechanism 4, comprising at least one mass 4a, 4b and at least one flexible or biasing element 5a, 5b, 5c, 5d, for instance leaf springs. The stator module 1 is contacted to a driven part 6, for instance a slider, at the contact point (A). The piezoelectric motor is designed such that contact point (B) is able to produce a closed trajectory, thereby inducing a relative motion of the driven part 6. The contact point (B) is moved by applying an electric field to actuators Ia and Ib and/or by applying an electric field to actuators 2a and 2b.

摘要： The present invention relates to methods for the batch fixation and electrical connection of pre-strained SMA wires on a microstructured substrate using electroplating, providing high bond strength and electrical connections in one processing step. The integration process here developed relies on conventional micro machining techniques and it provides an efficient solution to some problems that have hindered the widespread diffusion of bulk SMA to MEMS, such as the lack of cost-efficient integration methods of bulk SMA and the difficult electrical contacting of the actuator material at small scale. Also disclosed herein is a Joule-heated SMA wire actuator on silicon MEMS.
