Abstract: The present invention relates to an inertial slider (10) and a method for safely and controllably approach an object (2) towards a fixed object (3) for instance inside a transmission electron microscope (101). The inertial slider is controlled with a control signal (201) with a timing characteristic faster than a mechanical resonance of the object to be moved. The inertial slider moves in a first step away from the fixed object and the movable object is moved relative the inertial slider in that first step.

The sample holder comprise at least two arms each with at least one connector whereby the sample (206) may be mounted between the two connectors forming a bridge closing a gap between the two arms of the sample holder. The sample holder is arranged to provide mechanical forces to a sample mounted on the sample holder and measuring and/or applying electrical signals from the sample while at the same imaging using the transmission electron microscope. Each arm of the sample holder may comprise three substantially parallel beams for electro-thermal actuation.

Abstract: In recent years there has been a growing market for more universal analysis instruments. Analysis tools such as AFM1, TEM2 and nanoindentation work in similar environments. It is therefore possible, within limits, to use the same equipment to do all of these analyses. Conducting nanoindentation experiments in a TEM has also the advantage of increased accuracy compared to the tests done today. 1 Atomic Force Microscopy 2 Transmission Electron Microscope This project is focused on design and fabrication of a capacitive force sensor for AFM and/or nanoindentation measurements in a TEM. Nanofactory Instruments, the initiator of this, project, has developed a specimen holder for TEM that can be used for nanoindentation experiments. The measurement system used today has its limitations of being to large to be mounted in a TEM and thus an improved model was desired.

Abstract: This invention relates to a device for micropositioning of an object (4), e.g. for use in a microscope. The device comprises an acceleration unit (1) and an intermediate part (3), connecting said acceleration unit (1) with said object (4). The position of the object relative to the acceleration unit (1) is variable at high acceleration or retardation of said acceleration unit (1), owing to mechanical inertia of the object (4). Further, the intermediate part (3) has a first end (3?), being attached to said acceleration unit (1), and a second end (3?), being provided with an essentially circumferential contact surface (3a), and the object (4) is provided with clamping elements (4?). These clamping elements (4?) are adapted to clamp around said contact surface (3a) of said intermediate part (3) in order to hold the object (4) in relation to the intermediate part (3) merely by the clamping force and the frictional force exerted by said clamping elements (4?) upon said contact surface (3a).

Abstract: The invention relates to a device for micropositioning of objects, for example, in microscopy. The device comprises an accelerating means and a positioning unit connected therewith and connected with the object. The position of the object relative to the positioning unit can be changed at high acceleration or retardation of the accelerating means owing to mechanical inertia of the object. The positioning unit comprises at least two clamping elements between which the object is intended to be held merely by the clamping force and the frictional force exerted by these clamping elements.
