Abstract
The invention relates to a translation device comprising an actuator body and a coupling member which mechanically contacts said actuator body, the actuator body having at least one body of a solid electrolyte which is clamped between a pair of supporting surfaces and which is provided with at least one pair of electrodes between which mass transport takes place via the electrolyte under the influence of an electric potential difference, said mass transport causing the dimensions of the electrodes to change so that the coupling member is subject to a translation in a first coordination direction relative to a reference of the device. Preferably, AgI is used as the solid electrolyte and silver is used for the electrodes. On the basis of the above-mentioned principle, translation devices can be constructed for one, two or three-dimensional translations. Translations based on both translatory and rotatory motions are possible.
