Centimeter stroke at atomic resolution! Nanogears and other nano-scale elements are manufactured products made from atoms. The properties of these products depend on how atoms are arranged. If we rearrange the atoms in coal we can make a diamond.If we rearrange the atoms in sand (and add a few other trace elements) we can make computer chips. If we rearrange the atoms in dirt, water, and air we can make potatoes. The basis of Nanotechnology is micro- or nanopositioning. Piezoelectric crystals achieve high resolution down to the atomic scale. A drawback of this technique is the limited stroke of only a few µm. This drawback is overcome by the patented Nanomotor. It has a positioning stroke up to some centimeters while operating with atomic resolution and thus builds a bridge over eight orders of magnitude. The Nanomotor is a piezo driven linear motor consisting of a cylindrical housing and a slider with a free axial hole inside. It utilizes a piezo tube for fine positioning and a pulse wave produced by the same piezo tube for coarse movements. Every point of its stroke can be reached with a speed of up to 5 mm/s. Through its free axial hole the Nanomotor can transport a tip, a hose, an electrode, a hypodermic needle, a glass fiber or even a microgripper. The Nanomotor is available in three different versions. The small Nanomotor is half the size of a match stick. It can lift six times of its own mass. The dynamic force of this Nanomotor is so high that even imprints in diamond surfaces can be produced. Special versions of the Nanomotor can operate in ultra high vacuum, in liquid helium, even under water or as non-magnetic drives. Also visit http://www.nanomotor.de
