摘要： Various sensors use an electro-active device (11) electrically connected to a detector circuit. The electro-active device (11) comprises an electro-active structure in the form of a continuous electro-active member (12) curving in a helix around a minor axis (13) which is in itself curved for example in a helix around a major axis (14). On activation by relative displacement of the ends (16) of the device (11), the electro-active structure twists around the minor axis due to the fact that the minor axis (13) is curved. The continuous member (12) has a bender construction of a plurality of layers (21) and (22) including at least one layer of electro-active material so that concomitantly with the twisting the continuous member (12) bends generating an electrical signal detected by the detector circuit. The electro-active device (11) is advantageous as a sensing element in a sensor because it has a large displacement, high sensitivity and low compliance.

摘要： The invention relates to the field of micromovement measuring and can be used for recording creeping and dynamic infraprocesses both of natural and artificial origin, for example, seismic processes or infrasound and gravitation waves. The object of the invention is to raise sensitivity of measuring in a wide dynamic range. The micromovement measuring device consists of measuring element (2) and sensitive element (1), membrane (10), signal conditioner (6), the output of which is connected to the winding og the fixing electromagnet (4). According to the invention, the device is additionally provided with the pulling electromagnet (5), which interacts with the measuring element (2), the winding og the pulling electromagnet being connected to the second inverse output of the signal conditioner (6). The pulling electromagnet shall be preferably located on the membrane (10) that increases the range of the measurable movements. In addition, the prevention of formation of the oxide or similar films at the working surfaces of the measuring (2) and sensitive (1) elements can be provided by their hermetic sealing in space formed by the device housing (11) and the membrane (10). The method of converting movement to electric signal is embodied in said device; this method consists in the fact that the electronic field emission current is taken as a characteristic according to which quantization is made. The proposed approach permits the movements to be recorded in the range of Angstrom units.
